Email Notification configuration - 12.3.218

Email Notification configuration - 12.3.218

I just updated my OpManager server to 12.3.218 and now I can't seem to update/add profiles for email notifications. it gives me an error when saving it at the end...

"The input specified for the parameter fromAddress does not match the required pattern."

I'm assuming this comes from the From Email Address field? It's the same address I used before the update but it doesn't like any email address I enter... nor any other text I put in the field.
