"My clothes and my bag are black."
Translation:Pakaian dan tas saya hitam.
"Pakaian saya dan tas saya hitam", should also be accepted I think.
Please report it, so that they can fix it.
In the current translation, these two nouns are combined and attached to one possessive pronoun (in Indonesian), which is fine.
I think that's also allowed in English (My clothes and bag), but I'm not sure.
