Blend shapes in Skeletal Mesh but not in Animation Import

When I import my mimic from Maya, I notice that my blend shapes will come through when I put together my Skeletal mesh(so I could animate them within unreal itself if needed), but the Animation Export doesn’t seem to pick up those Animation curves, and the animation comes through without the blend shapes. I would like to avoid reanimating my blend shapes in Unreal.
for context, here is some of the specifics of my project:
-my animation is being done on a referenced rig
-I can only get animation out by baking the animation in FBX exports
-My blend shapes are driven by an SDK linked to a curve in Maya

Any tips or ideas would be greatly appreciated!
