Turkish language disappears from Languages menu even though it's installed after putting your config file

I am using P2812 25.12.2 version with Turkish language package preinstalled from firmware selector, but then I put the config file afterwards. Then the Turkish language just disappears from system menu, I check from the software it's actually installed but not selectable.
