how to to load all worls at server start

[teracube]

hi,

I created 6 worlds on my server : world, nether, ender, faction, lobby,rp
faction, lobby, rp were created with Worlds plugins
nether, ender, were created by TeaSpoon plugins

When i start my server, only 3 worlds are loading
When i stop my server, these 3 worlds are unloading

start server
2017-11-21 [10:27:10] �[Server thread/INFO]: Preparing level "world"�
2017-11-21 [10:27:10] �[Server thread/INFO]: Preparing level "nether"�
2017-11-21 [10:27:10] �[Server thread/INFO]: Preparing level "ender"�

stop server
2017-11-21 [10:27:06] �[Server thread/INFO]: Unloading level "world"�
2017-11-21 [10:27:06] �[Server thread/INFO]: Unloading level "nether"�
2017-11-21 [10:27:06] �[Server thread/INFO]: Unloading level "ender"�

On server properties level-name=world

How to configure full loading word at start server ?
