The view can see the top left assy yes and the rod, el-motor and some other brackets in main assy.
The sub assy's are copied along the rod but view only see the top assy. Tried to turn off shading and update the view, nothing happened (tried Quick, draft and Precice) - still bubble with ??
I'm ware of the the 'expand' and 'treat as part' button so this is correct in the assy.
