Method to change the sorting of weldment cutlist profile size?

 

I have a weldment profile with the following configuration, it is sorted in numeric order.

However, the sorting in the structural member drop down does not really follow numeric nor literal nor history based. I supposed the sorting has its own algorithm.

If I add decimal places for all the configuration name, it does fix the sorting.

Does anyone know is there any way to alter the sorting algorithm for this dropdown?
