Root motion Mr.Mannequin doesn't work in Anim Preview

Here’s my problem:

I did the root animation in Blender properly, and exported it with all the right settings. The animation plays fine in the preview. For some reason, however, the red line doesn’t show when I toggle show all hierarchy, and when I enable root motion, the character doesn’t stay in one place like it’s supposed to?

Any thought on what I did wrong and what I can do to fix this please?

Just found out the solution to my own problem!
In Blender, make sure to move the armature as an object and THEN set the key pose each time! I fixed my problem now!
