Custom texts and languages for Login V2

Hello! We want to use out-of-the-box Login V2 screen with custom colors and Login Interface Texts, however, when changing the setting in Organization settings I notice two things:

Texts are not changable -> seems like the Login Interface Texts targets V1 version of the Login, even though the Organizaion login step is set to V2 (default setting for Instance is V1, however). So I cannot customize any texts. The colors customization works okay, but the font I was also not able to customize.
Even though my theme has only Light Mode and English and German as enabled languages, the actual login screen still shows the controls with all languages in the list and day/night mode switcher.

I was wondering if both those are expected so far or I am doing something wrong?
Thank you! I tried using the AI bot and search on GitHub and here, but maybe I am not that good at searching stuff

Customized Texts (1) : Explains how to customize message texts and login texts at the organization level, including selecting screens and languages to edit.
Get Branding Settings (2) : Documents the branding API including theme mode settings and language restrictions.

hey @arrilight , this seems to me a login V2 problem
I tried running your setup and I really thought that I will only run into the issue that I have all the languages listed despite of only selecting german from the Login settings page but the fonts are also not changing, whats interesting is that it did worked consistently worked for the last few days. So I will check with my team as to understand what could be broken
