Membership Management Question

Club #573 - Northeastern Toastmasters Club
I am trying to update a member's email address. To no avail.
Once I tried adding again, I realized I incorrectly put the new address in wrong.
What do I do?

Delete the email address and re-enter the correct information

Am I missing something?
Where under Membership Management does it give you the option to delete?

Just hightlight and replace the bad email with the good email address.

I figured out how to delete.
Thank You!
I believe I have figures something out.
I am updating an email address with some capital letters. I have deleted and added again, but the letters are not showing as capital. Is that ok?
email address update is RonJoPik@gmail.com. It does not show the R, J and P as caps.
Is that ok? Will he still receive emails?

Email addresses should only be lower case. It will be fine.
