Importing youtube playlist fetches empty

Hello guys, I have the following issue:

I import this (and other public lists): https://www.youtube.com/playlist?list=PL31y7q49qYMDiiZeEwoX8vZpOsTX8p6gg

but it doesn’t fetch any videos. This list currently has one video, but it says 0 videos on Huzzaz website.

Any ideas? thanks
