Storyline 2 - buttons won't appear over video

Hi all -

I’m having an issue where something tested fine but now on the actual project I can’t get it to work.

I imported PowerPoint slides into Camtasia, added narration, published as an MP4 and inserted the video into a Storyline slide. I added shapes/buttons (over the video, on the same layer) with triggers that pause the video and jumps to a URL (to view another resource). I want the buttons to appear for a specified amount of time (the length of the narration for the “PP slide” referencing that resource) and then disappear. The video is 25 minutes long so I need to include the video controls. This worked fine when I tested it but now the buttons won’t show up when I preview or publish. (They do appear and disappear as desired when viewing in the timeline.)

There’s an additional issue with two of the buttons. They need to appear at 1500 seconds on the timeline but every time I enter that amount in the Timing box and click Close it reverts to 1000 seconds. I can physically drag them to 1500 but when you open the timing settings it still displays 1000.

Any ideas? Thx.
