How to limit UEFN game to single-player?

In IslandSettings, I’ve set Max Players to 1 and also enabled Spawn Limit and set it to 1, but, for example, a team of 2 people can still start and spawn into the game together.

How do I enforce only a single-player in the game?

I assume I’m being dumb and missing something simple. :confused: Thanks for any help!!

Interesting, I haven’t published my game yet, but I definitely want it to be single-player. From the language in the image, I would assume it would be limited to one. A bug? Let me know if you make any discoveries on this! I’ll do the same.
