Problem/Bug Multiverse, Lobbyapi, End not working.

So i recently started working on creating my very own server and wanted to have multiple worlds, i downloaded multiverse-core and lobbyapi to switch between my worlds, everything went fine, the nether was buggy but i fixed that with lobbyapis /generate netherandendfor command, but for some reason i always go to the default end world. If anyone has any idea how to fix this please tell me, if you need any clarification just ask.

Thanks in advance.
