User Registration new password not being saved in 5.1

I use the User Registration addon plugin version 5.1 and have a form to change the user password.

After I fill in my new password and save the form the password is not changed. Other fields like name do change.

When I downgrade the plugin to version 5.0 the password field does save correctly.

I recommend opening a support ticket for this issue at https://www.gravityforms.com/open-support-ticket/technical/

Ok thanks
