qgis - What causes OTB pansharpening ERROR Inputs do not occupy the same physical space?

When I try to use the OTB pansharpening tool an error comes up and I don not really know what the problem is.

I have a RGB and a Band8 map (both from Landsat8) which I want to use for the tool. All the maps have the same projection.
