I've noticed i can't remove values in a User Properties Field in Frontend User Management if i edit a user - I can only edit the value!
So if i have a User Properties "Internal Notes" and i want to edit the field for a user and leave it blank i can't - On submit it just refills with the previous value. I can however replace the original value with a new value!
I can see in the source code there is hidden fields which containing the fields values and therefore overriding any attempt to clear a fields value. The question is if i can remove the hidden fields in the edit template without messing something up?

Re: Frontend User Management - Edit Users fails
I have the same problem. Right now we just fill in a space but some templates check whether certain fields have a value.

I haven't solved it either 

Re: Frontend User Management - Edit Users fails
Right now I made a workaround in my site; fill in a single space when a field is supposed to be empty and check for this value in the templates.
Not pretty but it works until this can be resolved.
