No Spawns (Mob,Animal,NPC) (Pocketmine 3.6.1) (Bedrock Edition)

As the title says. Nothing Spawns. I have tried using eggs; Doesn't work. Even when I place spawners, they don't have the default pig or any other animal/mob inside. (And nothing spawns)

Info:

Software: Pocketmine 3.6.1

Game: 1.9.x

Plugins: Chestshop, EconomyAPI, Oregen, Skyblock.

Options: everything is checked except whitelist, pvp, force gamemode

It's a 5 player skyblock server. Me and some friends play on. Before I was using the default mcpe server software. And that had normal mob spawns.

Things I've tried:

1.Restarting Server

2.Checking options (both on and off and trying it)

3.Using /gamerule doMobSpawning (says use /help to see list of commands)

4.Eggs

5.Spawners

6./summon

Thanks,

Okay

It says it's recommended to use PureEntities plugin.
