Native wordpress password protection doesn’t work with ultimate member

Hello,
I have installed the wordpress plugin “ultimate member”, but now the native wordpress password protection for pages does not work anymore.

The page has no ultimate member restrictions.
Its status is on password protected.

When I enter the correct password of the protected page it’s not shown. Instead the ultimate member login (when I’m logged out) or account page (when I’m logged in) is shown.

How can this be fixed, so the correct page is shown?

Thank you very much.
