When applying the texture in the "Detail Albedo x2" the image is sideways on the cube, but in the texture preview the graffiti is right side up. Why is that ?
The preview window can be viewed in a 3d format. So you can rotate around within it. Not sure why it's showing up that way but it's probably just the view within the preview. Also the way the UVs are laid out on your object can also change that.
