SharePoint Server 2016 Microsoft Identety Manager 2016 With Service Pack 1

Hello Anyone

I Installed SharePoint Server 2016 + MIM 2016 With Service Pack 1

when I go to the AD DS Management Agent -- Select Attributes -- Selcet All

I can't See ExtenetionAttruibuite1/2/3 etc...

I Need to select them for Mapping Custom Attributes in SharePoint Server 2016 User Profile to them

I See many other Attributes that i use for mapping , but Spesific ExtenetionAttruibuite not Found

Any Idea?
