a possible explanation:
Not all texts in QET may be translated to your language, so QET falls back to the "Standard"-language in that place.

At that point you can help to improve QET:
Translate the "missing" texts to your language.
We would be happy if we could take over your texts! 

PS:
If you don't know if your question was asked before in this forum: Use Forum-Search.
In this case "language" would be the "magic word"!

I have a question about the software/translation. It installed in portuguese PT but has some mixing with another languages, is this normal?
Do i have some wrong configuration?
When i try to change the language it doesn't work.

i'm new with this software so i don't know if this was already asked.

I added a print of an example.

Best regards
