I have rotated the part and rearranged pin labels multiple times and now pins on PCB have multiple nets assigned.  This does not get fixed when updating pcb from schematic.  There's only one track underneath a pin with correct net name.  Example pic shows a pin having GND, STEP6 and SG6 where it's supposed to be only STEP6. How can this be fixed so the pin only belongs to STEP6?   EDIT: Since I replied to myself multiple times, here's summary that maybe of help to others: I had experimented with routing angle 'arc' which created small traces of the shape of pads that did not get deleted when track was deleted (probably because track was segmented into smaller pieces or because part of it was locked).  Notably arc segments are not classified as tracks so when viewing tracks only they do not appear.   They only show when arc are selected.
