Differential pair gap out of range: minimal gap is 0, autual is -7.84

It’s quite wired, the gap is negative value, is this a bug of DRC function for this DRC violation report item?
Or this is the correct value?

I do not know what’s going on there. It looks strange.

The latest stable version is KiCad V6.0.4 and there have been quite a few bug fixes in the last few months. I (sort of) expect that KiCad V6.0.5 will be released in a few days or a week or so.

Also, A minimum DP gap of 0 does not make sense.
What are your settings in: PCB Editor / File / Board Setup / Design Rules / Net Classes?

I remember some fixes to the DP code in early releases, so update to 6.0.4 and try again
