Dedicated server not starting on creative island

[Magnetar]

I have a multiplayer server from Low.MS and i am trying to get it going as a creative server that starts on creative island, but even when I set the base_island to island15 it spawns on the defualt survival island, Coastguard Outpost beginner. Can anyone take a look at my xml, or let me know if there is something else I need to do to set this up correctly. Here is my server_config.xml

<?xml version="1.0" encoding="UTF-8"?>

It's island_15.xml, not island15.xml
