Hi!
I have just found out, after hours and hours trying to figure out what happens, that in case you have some login modules, assigned to menu (in my case, to the different menus of different languages), it seems to be a bug when trying to access from guest, pages for registered users. It throws you to the login page, yes, but the title of the login page is not taken from the right login module, it seems it takes the first log in module it finds.
If you want, you can take a look at my webpage gutenberginstitute.com. This is what is necessary to do:
1) Go to courses - enroll in.
2) You will see a hipster Gutenberg proposing you to pass a level test. These level tests are for registered users, so if you click in any language to pass the test, you will be sent to the login page.
3) The login module is shown correclty only in English. In French, Russian and Spanish, everything is correct except the TITLE, which is Log in (in English) everywhere, independently of the language.
You can try this changing the languages from the floating panel of the right, near the canvas.
I have 4 login modules attached to the position "menu", each of one with a title in a different language. In the menu above it shows ok, but when being forced by the website to log in, it shows the English label and the rest in the correct language.
I attach you a screenshots as well of Russian (the component shows in Russian in the menu above, but shows the English label below).
Looking forward to hearing from you,
Jose
