Missing files, but it's imported

I am failing at this step in particular.
I uploaded 50 clips (i know not much, but it's a test) in a zip file to create my dataset, including metadata (with the text file) and the wavs. So i wonder why it's written "missing file" as it's included, i can hear it clearly and it works just as fine as all the others.

Thank you for your time. <3
