Oh. This is an annoying feature, but when you make a seek, if there is already an open seek that is deemed to be "similar" it will automatically pair the two clubs up together. However, this is a great example of when the two seeks are not similar and shouldn't have been paired. It is an odd feature, but not a bug.
I made the rating range 0-3000 for my club's open seek, and someone accepted it with a 1600-2000 rating range. Is this a bug? https://www.chess.com/club/matches/scaryninja-and-his-friends/1006910
