I was having an issue were custom fields were showing in the create a user cred form but not in the edit user cred forms.
I followed the instruction in an errata which required downloading a hot fix file and replacing 3 files. It would appear that after doing this it removed notification emails I set on cred forms.
Now when I go into cred to redo these notifications I have an issue of form fields not being available.
When I select option to send email to field in form there are no fields available in the drop downs.
Using CRED 1.8.2

I had tried the refresh button but nothing happened. I flushed cache etc, logged out and back in. Tried the refresh and it repopulated dropdown. Suppose was having a system issue. So it appears to be working ok. Still strange that I lost my notifications after applying hotfix.
