@Igor Eisberg On Redmi Note 5 Pro I have the same issue. If I change the preferred network type in settings - sim cards, after reboot it revert back to GSM/WCDMA/LTE. I notice this issue on 9.12.26 and 20.1.2

Here https://github.com/ygorigor/Romanian_MIUI_V6 I have translated xmls to romanian language.
If you want, you can use it in your weakly ROM releases.

I have romanian translation for MIUI V5 Android 4.2 (MTK phones)
It can be used in multilang patch, at least for dual SIM phones
