Get Material custom parameter using clockwork node

Good evening, I need help. I did this dynamo definition to get the material description list from a wall type or floor type, to numbering it, and to tag the wall(or floor) with the same numbered list.
It work good with the default revit material parameters but when I try to get the description from a custom material parameters containing a multilanguage descriptions the resul is a blank list.
Here the full dynamo flow.
