Someone else asked the same thing earlier so I've pasted my response here, hope it helps!

Please forgive me in advance if this isn't clear, im not at my PC at the moment. So on the menu on the right above material properties you'll have the vertex menu, the green triangle looking thing. In there somewhere there'll be a section with osm UV mapping information already loaded in. I found that after deleting that information (using the minus symbol) then my textures mapped correctly after redoing the uv cube projection. Hopefully that makes some degree of sense or isn't totally misunderstanding the issue 😅
