Region creator, what happened? (See picture)

[BethB22]

I am one of the beta testers. I am using the beta version.

So, I don't know if this is an error, or intended change, but it doesn't work... what now?

You're likely using a plugin

I have checked all my plug-ins. I don't have one that has anything to do with region creation. I am in the beta version.

I found the plugin that caused this.
