Try this in your sys.txt, maybe it will fix your problem.

[keyboard]
;skip_panels=""
skip_panels="qwertz,azerty,abcd,arabic,hebrew,hebrew_qwerty,russian,thai,hiragana,hiragana_qwerty,pinyin,vietnamese,turkish_q,turkish_f,arabic,Hungarian,Hungarian mobil,Ukrainian Number"

Also, in my opinion, there is no point to install this version since TMC isn't working.
