I am designing an RF PCB in Altium and I have set rules for 75 ohm as well as 50 ohm impedance traces. The picture attached shows a particular 75 ohm traces with error markers. The trace width is as specified by the rule and the DRC check does not show any errors. When I reset the error markers the markers do not go away. As you can see the traces are not the problem since the markers are also showing up on component pads.
I appreciate any comments.
