Georeference IFC File with different coordinate system

Hi,

I'm working with ArcGIS Pro 2.9 and I have a strange behaviour when I import a IFC File.

I have the same project exported in IFC and in first exportation I have used like coordinate system the WGS84 UTM 32 Nord and in the second exportation I have used the RDN2008 Italy zone as my coordinare system.

The project started from the same survey point but in the first file I have observe the point in WGS84 UTM 32 Nord and in the second the identical point has observed in RDN2008 Italy zone.

Reference point in WGS84 UTM 32 Nord

789471.0512163E
4646281.7997445N m

Reference point in RDN2008 Italy Zone

7040625.3072000 E
4635397.4217000 N m

When I place on the Scene my two file IFC I have a kind of rotation between the two files, but the starting point is identical.

The basemap in my scene has WGS84 UTM 32 Nord coordinate system and I have the stranger behaviour that I have described before.

Someone kwow why I have this kind of rotation?

In attachment of this post it's possibile to find thw two IFC Files that I have used for this post.
