New version - broke notification edits?

New version - broke notification edits?

Hi

On version 11308.

If I go to 'Notification Rules' and then select anything under' email templates for' (Replying to  Request for example) I get a big red error and cannot edit the reply notification. Doesn't seem to work with any of the 'Email Templates For:' notifications. 

Same result with Dev & Prod servers.

"Sorry an error has occurred"- anyone else have this on the reply/forward notifications at the bottom? Try to edit one.

I can edit any of the other notification templates (the ones at the top of the page).

**UPDATE** - you can try to edit many of the notifications and you will get the 'Sorry an error has occurred" error and your out without being able to edit.
