Webdav group error when trying to set user email from UI

Hello, I am trying to set the user email using UI. After click on save, I get the error “webdav: membership of this builtin group may not be altered.” I recently upgraded to 25.10.2.1 - Goldeye.

UPDATE: I was able to update the email using cli from the terminal by running account user update username email=bogusemail@dodgeit.com Therefore the issue is with the UI

What user are you attempting to alter? As it says, you can’t alter users that belong to the ‘built in’ groups.

UID=1000. This is a user I created for myself. I was able to edit this user using the Truenas CLI.
