Change heading on Category page

Hi there,

The heading of my category page looks weird and I don’t know how to fix it.
I want to get rid of the border and the black background behind the text. I also want to change the font and get rid of the word ‘Category:’.

I’ve tried changing everything in the Customizer, but it doesn’t seem to be in there.

Can anybody help please?
