Why do captions disappear on Storyline 360 slides?

HI Ron,

Thanks, but it does not address the challenge at this point. I've noticed that the captions actually have 2 yellow dots on either side of the timeline entry and that they can be adjusted. (much like a fade functionality)
I've removed the caption and inserted a new caption that does not display the "fade" feature and it now seems to be working.
Dunno how that "fade" feature was applied or selected though.

Regards
Z
