Cannot Load the data for this visual with aggregated data model

I have an aggregated data model that I recently pushed to production.  The data model and it's dashboards are split from each other.  So that we can have dashboards in multiple workspaces pointing at one data model.  

I have a very simple visual that is a bar/line chart that gives me a "Cannot load the data for this visual" in one of the split dashboards.  HOwever, I place the same dashboard/visual directly in my data model and it works fine (even gets it's data from the aggregated tables).  

I have tried deleting the data model and reinstalling it in the workspace, confirmed that the gateway is connected.  

Another kicker, the visual works if i switch it to a table.  But when I switch to a bar chart/line chart it fails and gives me the above error.

Any ideas or is this a support issue?

Thanks,
