Singleplayer permissions

I hosted a LAN survival world on a server. Made myself admin to change the world spawn. I hop off that world into one of my singleplayer worlds that have without a server. I go to change the weather and it says I have insignificant permissions, and I made that world on creative. Can anyone tell me what is going on??

No no there is no areas. I can’t use admin commands

I just had to enable console commands in settings lmao I forgot I turned it of lol
