I believe the typical expression for making noise is "kupiga kelele".
Indeed, do report it. Unaleta means 'you bring'
Duolingo should add an option to report that "this phrase doesn't belong in this skill"...
What does this have to do with this skill?
How about, "Unafanya kelele" or "Unapiga kelele"?
"Kuleta" means "to bring". This must not be an error.
