Hello, I've been having this problem for hours at this point. I've kept trying to troubleshoot and fix it but to no avail. Whenever I delete the world file, restart the server, have it generate a new world file, not only does it create the EXACT same world even with no special seed put in, it gives me a broken world with generations that make no sense to the modern naturalistic minecraft AND doesn't allow me to use command blocks (even if it says it's enabled) or any /gamerules. The only time I can actually use gamerules is if I download the plugin MultiWorld. Even then it only allows me to change a couple. This problem seems to occur with PocketMine. However, when I switch to vanilla Bedrock and reinstall the server in 1.14.0 (and delete the world again), it gives me an old world generation instead of "infinite". This basically completely disallows me to do anything on my server productive. If you need to know, the platform I am using for my server is server.pro. I will provide some screenshots below.
