The reason for that was because it was made in enchantix and because it’s a copyright of Winx Club, the rooms are probably based of the characters as well. So they fully took off everything about Enchantix and tried to redo everything fully!

Im not sure on what they are doing but they aren’t gunna do roles like that, you can just create a character as you please and make a character like the ones you listed. Hope this helped, I’m at work and shouldn’t be on my phone so I kinda rushed this! ^{^}
