Window openings not showing, solid wall instead

[3DG]

Hello, I’m putting a quick house together on a garden project and when I put my windows in my sketchup model they appear behind a solid wall. Even when I delete the wall and repopulate it with a blank wall (not brickwork), the brick wall still appears. I’ve unsynced, resynced and done a full restart, but the problem persists. Screenshots below, but if I move within the model it flickers and shows a bit of the window model on the same plane as the building face.

Hello. Please check if you have synced two models to D5. If you want to replace the original one with a new model, please click on the name of the original model when syncing and select link and replace.
