Is it wrong? "She had problems with the sound during her performance"

Your sentence is right (for understand) but it is not according golden rules.

Thank you, could you be more specific?

Tatka probably means that the translation should map the original's structure as closely as possible.

In my opinion Duo himself is a bit sloppy about this rule.

Yes, Duolingo usually tolerates it. I think that's the right thing to do. Especially when the word order change is in this direction. "She had problems with the sound during her performance." is currently being accepted.
