Imported transitions not working
I have combed the internet for a solution to this and I cannot for the life of me find anything. I downloaded and installed a bunch of after effects transitions, which are supposed to essentially be drag and drop. Sounds easy enough, except none of them will work on my project. The clips simply hard cut as if I never added any transition at all.

I'm quite new to After Effects, so I'm assuming it's something super obvious that I must be missing. It seems like other people have had this same problem with Premiere Pro, but I haven't seen anyone with the same issue in After Effects. My compositions and the transition's composition have the same frame rate and dimensions as well. I appreciate any help or suggestions!
