[OPEN] Origin is hosting Gallery under old ID

Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? 1.87.40.1030
What expansions, game packs, and stuff packs do you have installed? Installed packs do not have anything to do with my problem. I have some cc-content downloaded, but I do not publish modded content on the gallery. I believe some eyelash cc or skin textures do not affect this.
Steps: How can we find the bug ourselves? I changed my account name on the EA page, like advised. Once I changed my account name, it showed on the top left corner. But every time I release a new build to the gallery, it still shows my old account name as the maker. So the gallery has my new account name, but it does not transfer in to individual builds.
What happens when the bug occurs? My old account name shows in every item I publish to the gallery, even though my new nickname shows on the top left corner and on the tabs on top of the gallery page.
What do you expect to see? My new account name in my individually published builds instead of my old account name.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? No
