Converted FNC to UEFN now its stuck on Single Player when I publish even when I have set to 50-40 Players on MY end

Converted my FNC map to UEFN, now the max players is set to 1 (meaning its “Single Player”, on my PC the max players was 50, then I reduced it to 40 on UEFN thinking it just needed an update, I checked if there was any Verse files, Island settings, or any devices that would interfere, I can’t notice anything, I even wrote an email to epic, to which I’ve been sent here.

My map is called “Jam Verse” 2214-4070-0866

And in websites like FortniteGG it says “Max Players 1” which again, makes no sense.

I found the fix… I fixed it, so for some reason UEFN is a little different, and I just started using it so I didnt know, you need to make it Cooperative AND Dynamic for it to be matchamking and not Singleplayer (AS LONG AS OTHER SETTINGS ARE GOOD)
