All of my transitions in iMovie are missing. Was there an update that deleted them?

This has happened to me too. I usually have to close out, and open back up. It takes a few minutes, eventually catch up to opening with the program.

Thank you for this! Was pulling my hair out. Quitting iMovie and reopening worked. Hope Apple is going to fix this.
