Collection widget returning nulls

I am having a strange twofold issue with the collection widget in one of my mashups in ThingWorx.

 

The first issue is that I have to press the refresh button for the collection widget to display all of the desired mashups (some of them do not appear).

 

The second and more important issue is that when scrolling, some of the mashups within the widget drop out and go blank. They can come in and out as you scroll back and forth.

The data in the widget is coming from a SQL server with a number of services calling it. I'm not sure if that's part of the issue.

Make sure that the field you have selected as your UIDField actually has a unique value for each row. This behaviour typically occurs when your data set has duplicate identifiers.
