My question is originally about season 6. I just hate the whole storyline between Helia and Krystal. I don't know why they added it and old Helia would never be like this

He introduces Flora as a friend of him to Krystal.
But some people say it wrong translated and that in the original language (Italian) he introduces her as his girlfriend. Now I am wondering if that's really true. Does anyone know?
Are there any other translating mistakes?
I know there are many animation mistakes
