track width error

[Lucky-Luka]

I've disassembled the footprint and I've found a track under every first pin of the headers!
I haven't drawn them consciously...
Mistery
Now that I've deleted them all those errors are gone.

Only enable top layer to see it better. Then you can use Panels -> PCB Rules and Violations to browse through the errors

Hi all
I've placed all the components in the PCB. I've run the DESIGN RULE CHECK.
I've got width constraint error... I cannot understand it since I've got still no tracks in the PCB...
The error is referred to the first pin of the headers...
I attach the error, the image of the footprint of one of the headers with the error and the error shown as "< 0.3mm" (the min track width rule I've chosen) in the PCB after the error check.
Can anyone help me?
Thanks
