[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? 1.71.86.1020
What expansions, game packs, and stuff packs do you have installed? All packs installed but 1 (Journey to Batuu) and all 3 kits are not installed either.
Steps: How can we find the bug ourselves? My bug is gallery ID related. I have changed my Origin ID / EA ID I think in 2018 from Rosebudsim to Sleepdeeprived. My Origin ID shows correctly after the change, the gallery profile shows correctly too. However, when I upload my stuff to the gallery it reverts back to my very old username. It says uploaded by: rosebudsim.
