Center axis as a datum not repeat

browningdmis
So here is what my opportunity for the day is.

Got a part with a lager Id bore that is datum b. Going into the part morr is a smaller bore with a position of .003 to b.

So my fcf used the drf to control it. Well the report does not show x and z as zeros. Engineering says datum b is zero so the report has to show everything as zero. So I did an alignment using just datum b( center line of the cylinder) the report show zeros but bad position and does not repeat. What am I missing
