Cannot see schema exchange extended attributes

Cannot see schema exchange extended attributes

Yesterday we extended our domain schema with exchange procedures ForestPrep and DomainPrep.
Using 3thparty program i can see extened atrributes but using AD MANAGER PLUS 5 it seems that i don't have this possibility.
How can i manage these attributes with this software ?
Regards.
