[WPMU DEV Dashboard] Multiple Problems

I have several problems.
1) I was bumped from the live chat 3 times... after waiting forever.
2) All the keywords on the website are highlighted and underlined? How do I eliminate this effect?
3) The SEO report says that I have \"multiple\" H1 headings but there is only one on the home page? 3b) It says that to improve the SEO that I should include keywords in the H1 titles. The titles are keywords? 3c) Are you only supposed to have 1 H1 title on the entire website? There is currently one on each primary page.
4) The report also says to give attributes to the pictures on the page, but every one of them already have attributes, titles and descriptions?

Your assistance will be greatly appreciated.
