When I insert a humanoid into a viewModel im making, I randomly start flying around. It only happens when in first person. If I remove the humanoid everything works fine again.
Heres a video:

The games avatar type is set to R6, I dont know if that has anything to do with it.
And heres the viewModel:
And heres the viewModel script:

once you have the group created uncheck all the boxes in the viewmodel tab it should go from this 
to this 
next select both your viewmodels arms go to properties and change collisiongroupid to 1
