My Student Used A Premium Function & I Can Not Figure Out Where It Is...

I just taught Adobe Premiere Rush to a group of students.  One student's video will not render, because a Premium Function was used.

I first removed all the additional audio, then removed the graphics.  I also look at the video clip in the various menus and for the life of me... I can not figure out where the Premium Function or Asset was used.

Is there a way to show or highlight where the Premium Function was used.

I actually did not know that Rush had Premium Functions as I have been using it with my subscription for years now.  So, I thought Rush was just free.... little did I know that there were Premium functions.  So now I am desperately trying to figure out where she used something.

I even checked the transitions..... still have no clue.  Looked for little stars to see which one was Premium and nothing shows up.

Thoughts?
