@YGYL You've right. That is what I've discover earlier.
BUT
@Emmanuel Is something strange:
centimeterUnit must be the correct.
In this case CN & RU don't work as aspect but TW which have centimerUnit = work.
If change CN & RU to incorrect form = work.
I suspect it is also a misspelling in other place of translations.
How to verify and reproduce:
1. Open a home with rooms;
2. Set preferences to English & centimeter;
3. Menu->Tools->RoomsInfo ==> in table are m₂ => OK
4. Set preferences to Chinese or Russian and repeat step 3 ==> ft₂ => Not OK.
If change centimerUnit with centimerUnit in CN & RU files will work but it has no logic (at least for me).
