Electronic – Altium track width DRC error on corners

altiumdrcerrorpcbpcb-design

I just ran the DRC check in Altium for my PCB and I get errors on trace width for every trace segments on the board.

What is the reason for this ? It generated thousands of errors even tho all the traces are 4 to 5 mils wide.

All tracks width rules are set to >= 4 mils

This is the error message I get under "Rule Violations" :
Clearance Constraint (Gap=3.5mil) (All),(All)
Clearance Constraint: (Collision < 3.5mil) Between Track (52761.3mil,31343.2mil)(52769.499mil,31343.2mil) on Solder Side And Arc (52769.499mil,31340.4mil) on Solder Side

Edit: It also affects trace much much larger than 3.5 mils

It turns out it was in the clearance rule I selected "Any nets" by mistake which meant the rule was applied to any segment no matter what net it is from, changing it back to "Different nets only" fixed it.
