pcbnew-> Arc track distance error from board edge.

Description

I had made this project with an unstable version of kicad6 and in pcbnew I received only 1 warning.

Now if I run the DRC there are 3 errors of distance of the track from the board edge.

The traces are at the correct distance and also on the pcb there are other traces at the same distance but they do not cause such errors.

I think it is due to the fact that I have performed the arc connection function on the tracks
