The names of the axes of the Pareto diagram

Hi there,

I need help with changing the names of the axes of the Pareto diagram which is derived from Octopus.

when I change the name of the NUM components which are defined as objectives the names of the axes of the Pareto diagram do not change. 

I have also tried several methods, including restarting the simulation or continuing to optimize with Octopus, but still, there is not any change. 

I would appreciate it if help me to find a solution to change the axes name of the Pareto diagram.
