Mecanim x and z plane root motion not working when importing .fbx, but works with .blend

Okay I have a simple character with numerous animations imported from blender. They worked correctly with .blend file but I ran into a problem with it and had to use .fbx instead. Now y plane root motion gets applied correctly but no x or z plane root motion is applied. Hierarchy of my character is this: Wrapper holding animator script, rigidbody2d and animator -> colliders2d as separate gameobjects and character model with rig. Animation which need x and z root motion are not baked into pose. Controller is applied to animator and controller has been tested to work correctly with the .blend file. What I see is all y plane root motion gets applied correctly I mean all of it, every animation. But not even 0.0000001 variation in x or z planes. Walking animation for example has loop time and root transform y bake into pose checked everything else are default and it plays nicely. Thank you in advance!
