removing unnecessary coding from ColorWay theme

I actually have a few problems with my ColorWay theme and I’m really hoping someone will know what I’m talking about. My website is https://www.yourskinlab.com/facials/ if you’d like to see the problem.

1) There is coding that is visible to people who visit my site that I haven’t been able to figure out how to remove. It says:
`You may use these HTML tags and attributes: <a href=”” title=””> <abbr title=””> <acronym title=””> <b>
<blockquote cite=””> <cite> <del datetime=""> <em> <i> <q cite=""> <strike> <strong>
I don’t really know why it’s there and am really hoping that I’ll be able to remove it.

2) I just updated to the newest version of ColorWay hoping it would take the coding off, but instead it added a duplicate menu of pages at the top of my homepage. Where can I go to take that off?

3) I have been getting a lot of computer generated comments and would really like to weed those out as much as possible. Does anyone know if WordPress has the option to make people have to decode the scrambled letters before they can leave a comment so I don’t get so much spam? (I don’t know what that’s even called, but I hope you know what I’m talking about)

Thank you SO MUCH!!!!
