[MC-192065] Shulkers are spawning in overworld

Hello,

I've recently encountered a bug in Minecraft 1.16 in singleplayer mode. Shulkers are spawning in my world. I don't know where it can come from. I've quickly saw that commands in the game are not working like /seed.

I let you a Youtube video link here: https://www.youtube.com/watch?v=FwHu83KwmU4

I attach a screenshot if you want.

I give you THE world I used (37.28 MB): https://www.mediafire.com/file/pazq13wnr753lo5/Monde_en_1_16.rar/file

I don't use any datapacks, any mods, any command block or other.

I have also trying to re-create the same world and there are no shulkers spawning.

Where you using any mods like Fabric in 1.16?

No, I don't use any mods. My Minecraft is fully vanilla

In what version was this world created originally?

The world was created in 1.16 just after the release (not 1.16.1)

Please provide proper reproduction steps.

Ok I have maybe found the origin.

Steps:

Create a world in 1.16+ and go to caverns
Execute the command /datapack enable [non existent datapack] (like /datapack enable backpacks or /datapack enable pizza)
Wait 5 minutes in a gamemode where mobs can spawn
Search shulkers in spectator mode or another way

I repeat: Don't import datapack.
