# 75 Ohm trace with error markers in Altium

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.

• Right click on the trace with errors. On the pop-up menu, scroll down to the "Violations..." item. Hover on that (or click it?) and see which rule is being violated. If it's still not obvious what the problem is, edit your question with the information about the rule being violated. – The Photon Sep 25 '17 at 3:46
• This is the issue, it shows no violations. Just markers. I am baffled. – Nima Nikvand Sep 25 '17 at 23:15

Is the * column for the net checked in the PCB control pane, like this one?
