[Solved] track width error

[Lucky-Luka]

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

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

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.
