Sidesets, without variable data, coloring wrong

We are painting by variable incorrectly on sets, when we have partial arrays. What we are doing (I believe) is color by the last color we had, spread across the rest of the data. Here's how to replicate, and what I think we should do.

• Open attached file. All vars on. Turn on sets Unnamed set ID: 1, Unnamed set 2 and Unnamed set 3. (Note to myself, Cal Kevin, PC)
• Unselect the one block in this dataset. The bug shows with this block set, but it isn't as obvious.
• Apply.
• Paint by Applied Pressure. Two sides of the cube will be red, one will be blue. The plane parallel with the blue plane has real data, the perpendicular one does not.
• You can see this through Find Data/ Cell Labels/ AppliedPressure, then selecting cells. The parallel plane has data (10), the perpendicular one does not.

What I want is for the side that doesn't have data to be painted in the Color Editor/ Color Mapping Parameters/ NaN Color.

Have Utkarsh ask me for this dataset.
