I have been looking into this, and it is due to the way that the histogram filter is changing the column names of the vtkTable. The state loading logic in the vtkSMContextNamedOptionsProxy stores series properties by column name, and ParaView seems to be assuming that column index is fine (as it only sets the visibility on the first run). Just looking into the best way to fix up this logic to deal with histograms.

Commit c4469d7 has a partial fix for the issue - it keeps both column names constant, and so this issue goes away. I need to modify the default visibility when averaging is turned on in the proxy, in order to fully fix the issue.

Commit 9dc9a63 resolves the last part of this, changing the default visibility of the columns when plotting histograms. Not sure if this is a little hackish, as it is changing behavior based on the X series name but it does behave as expected.
