Translation of login.php not working

Hello team,

When I try to access the login page through my menu, I cannot click on it, I see a forbidden sign hovering over the menu item.
I manage to still access the page through translatepress, by filling in the form I put in a widget on the side of a page and not filling in the correct password, then I get redirected to the login.php page and I can access all items. However, the translation only appears after saving for some of the items. For example, the ‘Login’ button was translated, but the translated text (Spanish) never shows up. The other translations that do save and show after saving still do not show when accessing the page again. The translations appear in the translatepress sidebar but not on the front end.
Can you please provide some insight in what is happening and how I can fix this? I scanned the entire internet and could find no solution. I also use Loginpress as a plugin, but deactivating it does not make any difference and I am out of ideas.
