Delete a surviour that is a GW defender?

Hi all,
I have lvl 10 so I'm not playing GW Wars at the moment. But if i try to delete a surviour i get an error that this is not allowed, because the surviour is assigned as a Guild Wars Defender. Guild Wars not Outpost... i have never assigned a surviour to GW because it locked because I have only lvl 10. What can I do now? I would lile to delete lne because i found a better new one ;) 
Thanks
