[Paraview] Unexpected measurement appears in 5.4.1 but not 5.0.1

[Joe Ping-Lin Hsiao]

The attached image shows the unexpected measure with text. I tested two
versions of ParaView and it only happens in 5.4.1 but not 5.0.1.

180 stacks are loaded and set to volume rendering by my Python script,
which is also attached.

Thanks,
Joe
