3 Specific Items – Need Help

Hello....the domain I am working on, I have a few items I can't seem to figure out via the "Pro" version. 1) How do I remove the word "Archives" at the top of the page...If anything I'd rather it say "News" even though the page header is below the slider. How do I rid the page of the header "Archives"? 2) How do you remove the "Search" bar from the menu full stop? 3) I am having some issues with the mobile menu. I have the site how I want it color wise, but the popout menu is white, and so is the menu base text...You cannot see the option unless you mouseover. How do I fix that without messing up the main menu when viewing on a PC? https://www.nicholasandfriends.org
