Same for me. Here's my server list, showing Training and Invasion modes when I have those turned off in my filter.

Servers also rarely show when they have a queue. Very often I'll click on a server showing 97/98 only to be put into a queue, sometimes with 8+ people in it.

@spiral nimbus @final herald it's a little confusing, but server filters do not filter out what game mode is being actively played-they filter out servers that have that game mode set in their server tags that are manually set by the server team
look under each server name, you'll see languages in Orange/yellow, followed by game modes that the server plays in blue. That is what it is filtering by, not the current game mode being played

Ah... that's not very intuitive

yeah, it's definitely not a super refined system
