Can't restore events from trash

I can't seem to restore any events from trash. I get an "Access Denied" message. I have tried as superadmin, and I've tried in "switch to" mode, as the user who created the event. Same thing happens in both cases.

I've enabled support access -- hoping someone can help me figure out what's going on. I'm having some other issues with E+ (which I will post separately about) and in order to troubleshoot, I have to be able to delete and restore events.

Thank you.
