Cannot quite get my head around uploads to Mixter Plus.

I go through the add a mix process in MP and it seems to go OK but apart from a message that says hopefully the upload works, the mix does not show up anywhere. Two days later it is still not showing. Also on my previous mix I added a separate vocal track on the old CCM site which did eventually show up on the Mixter Plus page but not when you search for Pells only. It has this morning appeared in the pell menu.

Is it me or are these just teething problems with Mixter Plus
