Turned Camera Mode on once now all my new worlds have me stuck in spectator

I went to turn on the being able to crouch under 1 block and the unlocking recipes experiments and scrolled down to see the camera option. 

I figured it was like a replay mod type thing so I clicked it on to find out the world generated in spectator and wouldn't let me switch my game mode. So I exited out and made a new world, didn't turn on any experiments, and again spawned in spectator, unable to remove it. 

I proceeded to close out Minecraft and load new worlds multiple times and now everytime I load a new world I spawn in, in spectator, unable to switch my game mode.
