Root with socket attached doesn't move in AnimBlueprint

Hi. I have UE4.18.

Seems another guy had my same problem:

Unfortunately, yes… I already set all the parameters which the user Bizmark saied in his response
but It doesn’t work in the anim blueprint, while the animation plays correctly only opened the Animation sequence file…

The animation was made in UE, it has only the root_jnt as child one socket.
I made this because I need to move a flipbook depicting a weapon by a root bone, to re-create the HandBobbing of the firsts DOOM.

I don’t know what to do.
