Drop-down List Error

Hi all,

I’ve been testing a feature of Action Center and i’m finding out an unusual behaviour. I’ve set up a “Drop-dwon List” with the String() → {“María”,“Belén”,“León”} and i’m having some troubles while selecting specific items in Action Center.

The initial appearence of the Form is:

If i want to delete any user, for example “Belén” and “León”, the result is:

As you can see, both options have been disappeared and i can’t selecting them again. The issue is that, a user can have a mistake and delete an user and after that, adding it again.

¿Is there a bug detected on this feature?

If you need any more information, just say me.

Annex (form settings):

Thanks in advance!
