Animations not playing properly in Nested Artboards

I have made button animations. Each button has it's own artboard. I wanted to test out multiple buttons at the same time to see how the animations are looking together. So I made a new artboard and added my button artboards as nested artboards. But the animations aren't triggering. I have faced this issue in the past, but it has been fixed on its own without me doing anything. This time the issue is persisting.
