"No Categories" displays on main page

Hi,
“No Categories” displays on the main page, even though I have a category and have posted under it. I’m not sure how to remove that.

the webpage is https://www.hafences.com

In fact, my category actually shows up on the main page along with “No Categories”.

Thank you for your previous help as well,
HA Labor

Oh, and also, the Category that does exist has its title listed twice on the main page. How do I get rid of that too?

I’m new, sry for the troubles…
