No Home Button on home page…Unable to add About Button

Hello,

I’m having an issue with the Time theme. On my site…the home button doesn’t show…and I haven’t been able to make the About, Portfolio, or Contact buttons show at the top of the page either…like it is here on the theme demo: https://demo.s5themes.com/?theme=time

Here’s my website: i-muse.co

Any help will be greatly appreciated. Thank you.
