Mutiple audio assets (NOT) and unable to download

Hi, i hope someone can assist.

I am busy making shorts in Adobe Express, like i have been doing for the past year. All of a sudden adobe have issues with me adding 2 audio tracks (one voice and one music) - i have only one audio on the track, as soon as i want to add the 2nd it says “You have multiple audio assets in the same location”.

ALSO, i am unable to download the short. I never had any of these issues before?
