Import asset and scale factor is set to 1 and cannot be changed?

Hi, I have tried importing multiple 3d objects in .jas, .3ds, .fbx, and none of them will allow me to change the 'Scale Factor' from 1 to say 0.01. I was under the impression also that the default import scale for Unity was 0.01. Any way the objects when imported will allow the other properties to be modified and stick however when changing the scale factor it allows a value to be entered but it is lost after the apply.

Any ideas?

BTW: using Unity 3.1 on MAC OS X 10.6.5

its 2023
and this is literally still a problem. What is happening?
