WOW Armory showing name change on other people's Armory Profile - Zero Privacy

Hello there, I paid to change my name a few months ago for privacy reasons.
When I visit WOW armory profile pages of other people I ran keys with BEFORE the name change, and hover over the Mythic Keystone Dungeons run, I noticed it shows my NEW NAME that I wanted to keep private.

What is going on here? This makes me fully traceable to my new private name and it is visible on everyone’s WOW armory profile that has run a key with me. This is a pretty awful privacy breach now I have to change my name again and I don’t know if it is going to show up on their armory pages again.
