OSD missing button (subtitles)

Hi
With this skin, and only this one, the OSD doesn’t show a button to choose (or activate) subtitles.
All buttons are there, except this one. I can choose audio langage for example.
I’m on a Nvidia Shield, Android 11, Shield experience 9.1.1, Kodinerds 22 (installed yesterday, after having used Kodinerds 21 for some years).
I disabled joystick (as suggested by some on reddit).
I tried other skins : the button (either to toggle or choose from a list) is there.
The problem is that Aeon Nox : Silvo is by far my favorite skin.
Anyone can help ? That would be very nice
Regards
