It's entirely random, sorry! There's a 50/50 shot between getting the base couples or getting Everett/Jeremy. It's nothing you're doing wrong, I promise, it's just that you have to keep trying to get the one you want. Sorry for the confusion! I hope you get the result you're looking for soon!
Also, just to be safe, are you loading a save from before the meeting ended or after? It doesn't do the RNG until the absolute very end of that meeting, but during the period where the meeting ends (aka as the screen fades to the planner screen) it's already decided.
Also also, your absolute best bet would be to start a 100% new file if you're going off of an old one. I know that sounds undesirable but if all else ends up failing you might want to try it. Good luck!
