Created "Hierarchy Field" not saved in Import Mapping File

Hello experts,

I want to save the mapping created after having imported categories via MDM Import Manager.

Everything works fine as I execute an initial import (In "Map Field" tab, I create a "hierarchy field" based on the three fields "Categorie Name, Categorie Name 2, Category Parent" and mapp the Split Hierarchy field consequently ).

My problem is as I save the Mapping and try to reuse it for a new Categories import, the former "hierarchy field" does not appear anymore. I assume Saving Mapping does not save created hierarchy fields...

Can anyone help me on this?

Thanks in Advance
