My element shows that there are 0 comm group 1. I
have added a navigation in my element, which takes me to inventory parts. So, when clicking on the “Comm group 1” in my element, it takes me to inventory parts, where there are some parts filling out the criteria for my data source condition. 
However, as shown my element says 0? 

I have tried to delete the data source and enter it again. Remove it from the element and add it.
