Other person open .prproj clip is repeated over and over again.
1. Lastest version
2. Windows (me) - Mac (other person)
3. I work on a prproj and when the other person opens every cut is the same beginning clip repeating.
Hi there my problem might be dumb but I don't see how to search for a solution, I'm working with another person and recently this happends.
I work normal and its supposed to look like this

But when the other person opens the .prproj file it look like this with that white triangle and each cut plays the begging of the clip every time.

How do I fix this please?
