My character DAZ 3D GF8.1 does not move his mouth or eyes

From DAZ 3D I export it in FXB, when I export it I enable the arkit to have the blendshapes, the system recognizes my character but it only moves the body, it is not the video because using the characters they have if they move their mouth, I have spent my credits trying know why if the system recognizes that it will do the facetracking the result does not have it, has anyone had something similar? Is there a way to verify this FXB and the names of the blendshapes before spending the credits?
