User listed as deactivated on a proof workflow

Hello!

I was troubleshooting an issue and deactivated/reactivated a user.  Didn't fix the issue, and it created another where the user is now listed as [deactivated] on the proofing workflow so they can't access some proofs.  I've tried removing then adding them back, @ mentioning them, changing their role, sharing the proof, and have gotten nowhere.  Any ideas or tricks you can think of to fix this?

Thanks!
