Gap is 0.2000 needs to be 0.2540.

I got error and i want to modify the design rule but can't find where. Errors are: Pad to Pad Error (P-P) between (593.5600 480.4300) and (593.7600 480.4300) on Layer "[Top]".
    Error between Component Pad IC2.4 (Net 'SCL') and Component Pad IC2.9 (Net 'GND'), Gap is 0.2000 needs to be 0.2540.

 

 

That is Strange, the gaps between pads is 0.2 and seems rule 0.254 is too big. I tried to change the rule but the software looks something wrong and the table looks shift inside.
