Synchronizing issues with Revit




When synchronizing some parts of my revit projekt to Twinmotion it disorts whole building parts. All the houses are identical and are grouped inside of Revit in 3 different subgroups. Most of the houses work fine, but its completely random wich ones disorts and gives a faulty display.
I’ve tried ungrouping without luck.

When opening a fresh TM projekt from Revit everything is normal.

Help, i have no idea what to do.
