IFC Imported from Revit: Rotation difference between "Open" vs. "Merge from file..."

Brandon-W_DWa

Our workflow calls for saving our MEP consultant's IFC models as a .mod file, then hotlinking into our Teamwork file for reference. I have one Revit MEP IFC file that comes in at a different rotation, dependent on whether I just "Open" the IFC in a new instance of AC, or if I "Merge from file..." into a blank AC file I already have open. The merge method rotates all geometry (almost about the ArchiCAD project origin) exactly 45° counter-clockwise.
  1. Is this something that needs fixed on the Revit side?
  2. Don't both options of importing an IFC file use the same import translator settings?

The image shows one ArchiCAD file, in which I opened the MEP IFC, and then another instance of the same IFC, but via "Merge from file...".
