Pixelmon 5.1.2 (MC 1.10.2)

Hello aternos team... i want to change the pixelmon configs on my aternos server, but i can't because i can't modify the software configs... i tried with the pixelmon config screen (In-Game feature) but it doesn't work, it only works in singleplayer. i want to plant more apricorns in one chunk because the default value is 16. Thanks
