I used cut and paste for email and postcode for an event.
That copied a unintended space at the and of both of them.
Removing the space, then completely retyping them both, did not reset the invalid email and invalid postcode message.
I had to go back to an earlier version to enter information and save from there.
We've not had any issues with this reported elsewhere. I just went through the process, put in an invalid email and postcode and then fixed them and it worked for me. So at the moment I can't reproduce this issue.
Can you provide me with anymore details as to what you did or the process you went through to see this issue?
