I try to reroute a “bad” routed track, and the track goes dual or triple. Is this a what it should be or a bug?
Another try:
I’m also running into this problem, it’s a multi-overlapping tracks that causes the replacement not to work, it’s essentially caused by overlapping tracks, and I can’t reproduce it, so I haven’t responded yet
Thanks, though I don’t understand the GitLab messages. Does this mean it’s all normal what is shown in my 2 short video clips, no issue?
Hayden’s link must be wrong…
I don’t understand this. What are you trying to do ? you are just drawing GND nets everywhere, putting tracks where you want them. Who draws ground nets like this anyway ? Seriously someone other than the OP explain the ‘Bug’ to me so I don’t come a cropper in the future and I can upvote it. The video I saw shows someone drawing a GND track to a point then drawing again in another position all of which will be gobbled up by a copper pour anyway. I’m missing something.

This bug has been around for a long time.
If you want to re-route a trace, and you start in the middle of it, often times the router leaves the old trace intact. It is much better if you start from a pad, but I’ve seen issues there, too.
Still, it’s a really, really minor issue. I would never even think of complaining about it.

Yea it’s quite a minor thing, but happened to see it and thought hm this is maybe something strange. When I now know this can happen the best thing is to remove the complete track, I guess, remove all segments in that track and start again from scratch. But is this the meaning with this router? Maybe it’s the same in other modern brands of routers as well, Altium etc, so probably not much to complain about.
… and then another try:
Why would you make a track, then start from somewhere else and still it’s not good so move to another spot and start again ? why not delete the segments you don’t like and carry on or grab the trace and move it to how you like it ? of course in this case just delete the lot ? Honestly you do know that you can manipulate individual segments of a track and and move the trace all over, like if all you need is a nudge or two. Besides what if you want to do this intentionally ? like spelling your girlfriends name in traces on the board ? 
This is not really about how and why I route these wires, not about the art of routing. it’s testing of the current beta/release candidate, why not make the Stable 9.x as good as it possibly could be? If I do the routing “wrong” maybe the software could stop me from being this stupid.
what do you mean？ 
This bug is very serious, it seriously affects the use, and the resulting track cannot be automatically cleaned by the cleanup tool
I disagree. But, you are welcome to pile on to the bug report.
Yes, probably a bug, I sent the PCB file to a friend to import it in Altium Designer (which may also have added some more problems into the file through the importer) but even then this strange routing behaviour was not present there.
It’s only a bug if it’s not performing as intended . . . I see you just adding additional tracks.
You can set the Interactive Router to remove redundant tracks . . . if that helps ?
Cleanup tools won’t clean up the redundant cabling caused by this bug, just try it
