Apply video template not working

I am trying to apply a video template to my clips (43 of them) and it will not work. It says:

Info: Applying video template: 131016

Gopro Hero 4 Black Edition

Template loaded original_source
Template loaded media_source Gopro Hero 4 Black Edition
Template loaded price_amount
Template loaded Not same price for all sizes
Template loaded Has No Audio
Setting bins 900822
Error: Please stay below 1000 items in a bin

It says stay below 1000 items but I only have 43. Anyone else getting this error?
