How can I replace the player getting banned when eliminated, to instead being put in gamemode spectator?

I have should ban off and should spectate on but it still bans them:

elimination:
spectate:
killerDisconnected: '&cYour killer has disconnected!'
shouldSpectate: true
killerNotOnline: '&cYour killer is not online so you are not allowed to spectate!'
bans:
broadcastBan: false
broadcastMessage: '&c%player% has lost all of it''s hearts and has been banned.'
banMessage: '&cYou been banned due to loosing all of your hearts, your last killer
was &4%player%'
shouldBan: false
shouldEliminate: true
scaleHealth: true
healthScale: 1.0
environmentStealsHearts: false

shouldBa: true

shouldBa: true

It still bans them

I want it to not ban them

shouldBan: false
shouldSpectate: true
