After rename hero my armory doesn't work correct

Good morning,

That year, someone did not like my nickname, which lasted 6 years, and I had to change it. So, since then, when I renamed my maine, in the armory wow, that on the site, my character’s statistics are not displayed. I ask for assistance. I really want to know how many futile attempts I made, so that I couldn’t get an “indestructible”: D

Russian support sent me here, so please help.
