Something when wrong with your images, even when I click on them the images do not get any bigger. Aka I can't really see your views. That being said, it sounds like you might be hitting this issue Numbers Showed as Repeating on Worksheet When Blending Data
You might make sure that the active linking field is just the original ungrouped field. And then the grouped field can be used in the view.
There are several limitations with data blending. I typically recommend using joins (or cross database joins) to do a row level join the of the tables rather than data blending. See Join Your Data
Hope this answers your question!
