Description of the Problem

While adding multiple users under HTPasswd IDP definition, User has cleared or deleted previously added user definition. After this action, the "Add user" option is disabled for the user and the user can't add a new user from the HTPasswd IDP definition page in the UI.

Note: The issue appears only on staging not in production env. Hence suspecting that it could be regression issue on recent multiregion MR merges.
