Nested Animations Disappearing at the End of HTML5 Animations

[BigNic]

So I'm relatively new to Animate and am unfortunately working with a tight deadline. I nested two more minor animations into symbols to scale them proportionally into different google ad sizes. Unfortunately when I output the file the HTML5 and run them through the validator, those two symbols blip out at the end of the animation. I can't seem to find why this is happening, all I can speculate is that it has to do with the fact they were nested.

Unfortunately, I can't post screenshots due to legalities.

TIA.

do you see any problem when testing from within animate?

No. Everything runs as intended to the very end in Animate.

then the problem is with whatever that validator is doing.  eg, truncation to fit within the ad guidelines.
