Picture on Slide Delayed Appearance for 4 Seconds with No Explanation

Storyline360:  This seems to be a simple bug occurring, but I've yet to find a solution to prevent its occurrence.

I have a slide that has a Picture appear at 0 seconds right as the timeline begins.  Instead of appearing, the screen is blank and it then appears after about 4-5 seconds.  This occurs after publishing ONLY. Preview works correctly.  It's become very frustrating as I normally find workarounds when bugs occur.

Also, the issue does not occur when I insert a shape at the beginning of the timeline, the shape shows up fine but the photo still does not show until 4-5 seconds.

I've tried these things with none of them resolving the issue:

-  Use Pasted Screenshot instead of inserting photo file

- Insert new blank slide and copy all content from old slide

- Move photo just inside timeline to .25s or .5 s

- Remove entrance animation from photo

- Remove Motion path from photo (it does a slow pan)

- Have previous slide advance with next instead of automatically

- Some other things I can't remember. 

 

Has anyone else experienced this?
