I also tried creating two new servers, using a single different port for each, and was unable to reproduce the issue.
I tried that earlier and wasn't able to reproduce the issue either. Then as soon as I went back to using the default servers.ini, it was there again. So I played with the settings for a while and I think I found the source of the issue: It's the "Description" part of the servers. As soon as I put the same description for both of my newly created servers, the problem appeared (only when connecting via the toolbar, of course). Now this also explains the reproducibility with the default file: It uses the same description ("Random server") for almost every network.
While testing I noticed again that even though "move to top of list" was checked, servers/networks were not always moved to the top of the list in Connect -> Servers. This issue also only appears when connecting via the toolbar button though, so it must be part of the same problem.
Hope this helps!
