Weird Thumbnail Library Glitch?

Hello everyone, i’m currently using Harmony 10.3, and when i was making an action template for default poses, i noticed something weird with the thumbnail on the library. Whenever i generate it, it results in a collapsed-overlapping elements alltogether. Weird thing is when i dragged it to the desired timeline, it acts normal! No glitch at all ! Maybe it’s not effecting my work so far but maybe a little info on how can this might happen? I watched a tutorial and their thumbnails looks just as same as the desired pose.

Thankyou!
