URGENT: Maya Rigger needed

Hi, we have a rig that has a problem with the feets Z translation, on Object mode it point correctly forward, on "live object axis" it shows rotated like 15 degrees, not pointing forward like object mode, this what it does is when animating on graph editor only z axis, it is being translated diagonally instead of straight forward and back. Rig is built in advanced skeleton.

If you know how to fix bone orientation on an actual rig skinned, please write me it´s urgent.
