Cannot fix collisions

[EmmanouilKoreta]

I created the walls of a house with blender archipack, but when I export the fbx and import it to unreal engine it have these collisions. I want to be able to walk through the house but I cant fix it. I tried removing the collisions and adding them again but this is the only way the collisions appear. Any solutions?
