users cant edit prefixes
 

I've gone into prefix permissions and checked off the relevent user groups, and they STILL cant edit prefixes. we have a for sale subforum and there are various for sale prefixes and there's a SOLD prefix. ppl can choose their 'for sale' prefix on making a thread, but when they go back and edit it a few days later, they cant choose SOLD - there's no prefixes there at all.. and yes, theyre going to advanced editor. It's just not there :( help?
