Imported Blendshape animation from maya to unity keeps zeroing transform however placed in scene.

My blendshape animated polygon FBX models keep re-positioning themselves at zero transform when I play a scene. I've tried many export combinations from Maya, eg, frozen transforms, unfrozen transforms. The problem repeats. I once found a work-around by parenting the blendshape to a bone inside a rigged character, that might work again if I try it again, but it seems a sloppy way to do things.
Any advice would be great.
