Why does my social icon code move from the HTML section to the welcome screen?

Hello there!
I have a social icon code that I want on the front page.
The problem I have is that the code I implemented won’t stay at the HTML section, but jumps up to the welcome screen.
Is there any way to isolate the action for just the icons?
Would be very nice if you could help.

Psst here is an image…

I just want to learn so I can do it myself.

But thanks for your offer :slightly_smiling_face:
