My guild doesn't vinculate with my characters


My guild most important doesnt’ show in my profile so I can’t upoload Castle Nathria logs in the guilds page and they’re all in my personal logs.
My range is raider with this but I can see another guild in which I’m in the last range so I can’t understand.
I desvinculate my battletag and turn to vinculate but it doesnt’ work.

Character name: Ylya
Guild name: Le cryería - Tyrande
