importing audio from icloud to garage band on ios 10.3

Hi,
specs:
the latest version of garage band on latest ios.
first, open garage band. Home button will on the left, and then find the menu button, top left, then choose my songs. Then, find the new button, and there are two choices given, one is to create new and another is to import from icloud. If i choose ICloud, and then it will give my files inside icloud, so i for example take an audio file. But if i double tap, nothing happen. It never select the file. Can someone verify this? I want to import audio files from icloud to garage band, maybe there must be in some format only for the file that is going to be imported?
