DRC: shape to route keepout spacing

I have fiducial marks on my board and i am getting error under unassigned shapes/drc as shape to route keepout error. There is no route close to this fiducial.

The orange line is my route keepin boundary. When i move this boundary such that fiducials are outside this boundary, then i am getting

additional errors as shape to route keepin. How to get rid of these?

Here's my fiducial -

1) Top etch pad; in the pad editor I specify a 'Keeput' region (to keep etch away from it); Make sure the soldermask gets pulled back to expose the pad and clearance to copper too.

2) Have a DFA Place Boundry defined for it the size of the soldermask pullback

3) In the layout I have a DFA Constraint to keep any components away from them

Easy, quick, simple.

Good day.
