Character stuck with 1xp to level

I couldn’t find a proper ticket category in support but, one of my characters is stuck with 1 xp to level. I’ve checked in Stormwind and XP is not turned off. I’ve killed dozens of things and turned in a couple of quests and nothing will level me.

is the character level 5? of so its becus you dont owne that champion you need to buy him/her to go over that level

if your not talking abute starcraft 2 just ignore this

I definitely own him. He is level 35.

in that case i have no ide
