Custom Dynamic Head Importing Error

So im having an error with the new feature, which im trying to import a dynamic head, and i followed the tutorial in the devforum, but it says it should be imported with a face controller already, but mine doesnt and is imported just as an normal rig with bones and etc
how it should be - > image
how it is → image
how it is in blender when i export →

i also followed all export settings like disable some animation baking functions, tail bones etc
