Pipeline save and Catalyst dumps inconsistent

I’m using Catalyst for In-Situ visualization of astrophysical hydrodynamics simulations. The position of the colorbars generated in the GUI while creating the Catalyst pipeline script (Catalyst state) looks fine. However, on using the script to make on the fly visualization, colorbars get shifted to some other location. How to fix this and why is it happening?

Hi! Anyone has any clue what is the issue? I’m pretty much stuck here and out of ideas.
