Why some Widgets doesn't appear on Android?

I packaged my project for the android multi plattform. I created overlapp events, which sould create widgets, which are shown in the viewport. But they doesn’t appear on android devices. Only on windows. Also widgets should appear, when i pressed on buttons(only one button from the hud appears, but the others didn’t), but this also doesn’t work. On windows all works great.

Need help!

Thank you:)

Can you show us the code for where it creates the widets and what triggers them to create, and also tell us if the widgets are put in the corners of the layout and what kind of anchors they use?
