Can no longer turn the video compression off with new Storyline 3 update...

If you’re wondering about the video codec, the dev team’s responses are a bit cryptic. Baseline, Main, and High are like versions of the h.264 codec that support different things.
But there doesn’t seem to be many others (Adobe Media Encoder) or in most cases any others (Handbrake). But regardless, anything else is non-standard - so when the dev’s say SL supports anything in using those 3 profiles, you can pretty much interpret that to mean SL supports any mp4 with the h.264 codec - especially of you've chosen any existing preset in a video conversion program.

So codec isn’t likely the issue. In my file I have the same issue as others and I’ve done a bunch of testing that I'll outline below.

Setup:
I have an existing Storyline project file in which the video compression options are greyed out and stuck on auto. This is an issue not only because it’s recompressing my videos and thus lowering their quality, but also because there are 4 videos in the project… so instead of taking one minute to export each time, it takes 30 minutes. Every time.

It’s not the codec:
Using one of the same video files, I created a new Storyline project and imported it again. It didn’t have the error (I could change the compression options).

Therefore, I now have…

The Existing SL file: Video compression options greyed out and stuck on automatic.
The new SL file: Video file allows for adjusting compression options.

Both using the same video file - thus, it’s not the codec.

Following that, here’s everything I tried after - but I found no solution.
FYI: I’m using Storyline 360 v3.30.19518.0

What I tried in the existing SL file that didn’t work...

• Replacing the video
• Importing the video again on the same slide
• Starting a new blank slide and importing the video again
• Deleting the video and reimporting
• Deleting all videos before attempting to re-import one.
• Deleting all videos, saving, closing storyline and reopening file before re-import the video again.
• Going to publish settings, and in every tab clicking on on “Quality” and setting all video compression to standard.
• In the player settings, changing the Player Style to Classic and in Other, trying both “Lock player at optimal size” and “Scale player to fill browser window”, 
• In the player settings, changing the Player Style to Modern.
• Saving the player settings from a file without the error and and applying them to a file with the error.
• I also tried doing each of the above one at a time and closing the file and re opening.

What I tried that partially worked...

I also tried saving the file as a template file

• When double clicking the template file…
  • I select all files and import, a new document is created automatically and this still has the same issue (compression options greyed out and stuck on auto).
• When starting a new file manually…
  • If I immediately create a new slide from the template slide that has the video on it, it still has the same issue.
• BUT...When starting a new file manually…
  • If I import the video file manually, the issue ISN’T present, then if I create a new slide based of the template slide with the video on it, it too DOESN’T have the error.
  • This isn’t much of a solution because it still requires recreating the rest of the project (so depends on your project). It’s included here in case it can help anyone or help the SL devs fix this issue.

Note: I tried this the other way around too. Ie. I saved the version WITHOUT an error as a template. Then I opened the file WITH the error and created a new slide using the error free template, but it unfortunately adopted the error too. Also tried using import and this didn’t work either.

Good luck everyone.
