Meeting Registration Qs have disappeared and text can't be added

There appears to be an issue with the Registration Questions function under Meetings. I have a Meeting Template that includes three Qs.

For a specific event, I just noticed that the text of the questions has disappeared. When I try to edit/add them back, the text field doesn't allow me to enter anything.

I have tried both in Google Chrome and in Firefox to no avail.

Is anyone else encountering this issue?
