I have an interface to track our sales, and I group the results by "Source".
Source is built in Customer Records, then linked into Quotes, from there it is linked into Sales. My data still shows grouping within Customer Records, but stopped displaying the data in my Sales graphs (it was displaying fine until 4/2).
As you can see, the graph populates with the correct premium Y axis, but the data doesn't show up as it does in leads. When I deselect grouping by source, the data populates, but disappears when I group by source again.
