Kreo – Main menu, header bar menu and text color higlighting

Hi
I’m new with your kreo theme, so in the beginning I will have a lot of questions.

1. on the top of the pages is still this small white: written Buy Now Buy Now Theme Overview Theme Overview WordPress Hosting WordPress Hosting

How can I delete this words?

2. I want the menu from home till contact written on the top, and not only the sign for menu.

How can I enable this?

3. If I change sentences in a portfolio item (let’s say: Typography is just not enough)
Typography is just not enoug is written in grey and black.
When I write there a new sentence, it is just grey.

Why? How can I write sentences in different colours?

Greetings and thanks for help.
