Hello,
1) You had 2 headers https://prnt.sc/1tgmi6p One for all the pages and another one for the home page only. I removed the home page header.
2) I have changed the footer logo and it works https://prnt.sc/1tgn5vo . To edit footer go to Static Blocks > edit footer static block using Elementor page builder.
3) Edit Socials static block and change the color https://prnt.sc/1tgnhbm Edit Coffee – slider services block to change services.
4) It’s ok https://prnt.sc/1tgnr6j
I suppose issues were related to Multiple headers. You missed that the additional header was created and edited only the default header.
Regards
