My pet dungeon Toybox gateways not working

So I've built my own dungeon and I can't figure out how to get a party to spawn from the toybox gates. When I test the level it tell me that I have to kill the current wave first before I can summon a wave, however I never summoned a wave in the first place. Everything else works except this part. Super stoked to get it working though so I can build more pet dungeons.
