Short description of error
When exporting an FBX the transformations are inconsistent. When exporting an object on it's own or with a single empty the result is fine, but when you have two empties then the object has the wrong orientation. I have put together an example blendfile.

Exact steps for others to reproduce the error

Export example 1 using the settings shown bellow, then export example 2. The first one is okay but the second one has the wrong orientation and scale. This can be seen when importing into other applications or importing to blender itself.
I use these export settings:

[Based on the default startup or an attached .blend file (as simple as possible)]

Export Test.7z

This is caused by the Apply Transform option and as commented in #65478:

Thanks for the report, but that Apply Transform option is known broken in pretty much anything but basic use cases (static meshes without any fancy relations or anything). That’s why it’s marked as experimental, not a bug, just some TODO to get that actually working…

So a known issue.
