Some issues on my website

Hi folks,

I need your help with some issues on my website. Working so long and hard by using this forum on my website. The community is great!. Everything else is working fine and I am very happy using this theme.

1. In the mobile version there went something wrong. I want the logo only here centered. Under that logo, there should be also the centered mobile menu. The links in the menu need also more space and should be centered. Now they are somehow at the very right.

2. I removed the icons in the meta descriptions of posts, but in the mobile version they are still visible. How can I remove them also there?

5. I want to have thumbnails like in popular posts next to the buttons that link to older or new posts at the end of a post. Is that possible?

4. Not so dramatic, but the scroll to top button, that appears on the right bottom if you scroll down a site is missing somehow in the desktop version on other pages, except the gallery (my starting page). In mobile version all is fine in with it.

Thanks for your help.
