Hello,
1) Make sure that you edit home page header https://prnt.sc/13467d2 and save home page header https://gyazo.com/386f6118b858074dff462eaf5d8be3a1 not all the theme options. In case you save all options you save home page header but then you are redirected to the default header editing screen.
2) I see the HTML block 2 area for the home page header https://prnt.sc/1346ap9
What browser do you use? What address do you want to show there?
Regards
