Hello.
I wanted to change a particular BP setting of the Pokédrock mod ( to Allow Vanilla mobs as this mod has a setting in its BP to keep or remove mobs via a slider) so I made a singleplayer world first and changed the BP settings (via"⚙️" icon) while manually installing this mod in-game.
It worked perfectly.
Then, to make it work on Aternos, I then uploaded the zip file of this singleplayer World (with the updated setting) here after creating a server.
However, once I entered the server, I noticed that the BP settings reverted to default (Mobs OFF) and also I couldn't use OP commands like teleportation, gamemode or time anymore... Even though Cheats were ON and I gave myself the OP via "Players" in the server settings.
Can anyone point me what could be the mistake here? I've been at this for hours now. Thanks in advance. 
I'm using Bedrock Edition 1.19.50
