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?

    HI, your fiducial should be built with a "route Keep out", on all layers. not "route keep in". This should fix your problem., i hope this works for you. Cheers

    You can't "completely" fix this because you have placed the Shape of the Fiducial and then surrounded that with a Route Keepout. Route Keepouts don't allow Shapes so you get the error. Waive the DRC is about as good as it gets. You could add a "Shapes Allowed" Property to the Route Keepout but this could, potentially, allow "any" shape into the Route Keepout, which would be undesirable.

    Hey, after I have seen your comment. I went back into my fiducial to see how I made my part. Because I never get those DRC;s.  I made the part using a mechanical SMD pin instead of a shape.
