old profile pic and name

[ORGASMA]

Hello! 🤘😀
When I registered here in the forum 2 years ago, my profile picture and my username were adopted automatically from HH.
Meanwhile I have an other username at HH and an other profile picture.
Now my questions:
Why were the picture and the username not adopted during the change? 🤔
Is there later no more interlinkage between HH-account and forum-account?

I've seen, that I can change here my pic manually... but not my username...
