Tertiary axis/plane is parallel to primary axis

So I have been having a problem with this part. I have been trying to get the position dimension on the 0.266 holes (in the middle holes compared to Dat D, Dat B, and Dat C) but I have been getting the "Tertiary axis/plane is parallel to primary axis" error. I am using one alignment for all the measurements with all 6 degrees constrained and marked all the work plains for the different sides.

Anyone see anything obvious that I missed or have anything I should try?

This DRF is invalid. PCD will never let you use -C- in XACT Measure because all 6 degrees of freedom are already constrained by your primary & secondary.

DBC interpreted literally would mean Level Z+ (or Z- depending on vector to Cyl_D, rotate Plane_B to Y+ about the direction of -D-, make -D- X AND Y origin, and make a plane or point on top face to set your Z origin. -C- would get entirely ignored as tertiary.

Thanks a lot, I haven't heard the CAN-MAY-MUST thing until I was looking up stuff for this problem. You are saying that adding Dat-C- is redundant because it doesn't add any new constraints.

And PC-dmis just doesn't like that I guess?
