max exporter does not transform instance node properly

In 3ds max 2019, I have a scene and export to babylon file, some replicated nodes appear to have offsets, maybe the instance transform not export properly, I'm not sure what is going on or how to fix.

[Untitled.zip](https://github.com/BabylonJS/Exporters/files/9061745/Untitled.zip)

Start by opening Untitled.zip in 3ds Max 2019 and reproducing the export to a Babylon file. Compare the transforms of replicated or instance nodes with their positions in the source scene; the issue is done when the exported instances no longer show offsets.
