Virtual Channels - All Videos Not Importing to Lineup

Apologies if this was asked before, however I cannot find any reference to this question.

I have a virtual channel with 780 items, but only the first 157 items are coming back in the guide and then starts back at the first item. In the virtual channel setup screen it does show all 780 items. I also took a brief look though the logs but haven't found anything helpful to explain or troubleshoot.

Thanks for the help!
