What happened:
I tried to find some SAX sounds on your 2nd page NORD USER SOUNDS. So I started a search with the keyword "sax". A list appeared...
In the list I opened the deeper information (dropdown) of SOPRANO SAX ( 50343) and also BRASS SAX (1296). At the end I decided for BRASS SAX and wanted to rate it with 5 stars.
But my stars looked like not beeing accepted. So I tried again and again. Suddenly I recognized, that the (still) open SOPRANO SAX got all 4 ratings.
Now I closed all deep informations except this of BRASS SAX and rated it again with 5 stars. Now it worked.
