BUG::MATRIX VISUAL::NOT DISPLAYING COLUMN

My guess is that the new PBI Desktop update for May broke something AFA the Matrix visual is concerned.  Because the previous version of the report running in the Service is showing the Class field in the Matrix just fine (granted all tables are in Import mode).  

Or could this be related to the fact the DimClass[Class] field is a calculated column (created in PBI Desktop) on a DirectQuery table from a LH?  --> It's not: I just add a similar field from the fact table, ie FactTable[Class], which is not a calculated column, and it too does not show up in the Matrix visual.  

So definitely something to do with the new PBI Desktop update would be my guess.
