Hubshare charts are not working when State is used as a property for grouping

Hi community, 

M-Files support is looking into this, but I am wondering if any of you are experiencing the same problem that I am facing.  I had some charts that were using the workflow STATE property to display the number of items in that state.  Since January, these charts are failing.  

This is how the chart looks when using the state property:

And if I select another property to group, it looks fine.
