Imported meshes have inverted XY-coordinates?

So i made a playground with my own model of a cube (10x10mm) in positive coordinates. I checked several times.

Then i add an AxesViewer but now babylon shows the model as it is in negative coordinates?
Can i invert the axes? Still if i can, why does my positive coordinate model appear in negative coordinate direction in babylon?

Here my playground: Babylon.js Playground

ok, never convert gltf to babylon by opening it in the sandbox and then exporting as babylon file… Blender babylon exporter works much better.
