Looking to change the font and turn off the upper slider

Hi hope all are well!

I have an interesting thing here. On the homepage, the top bar is referred to as the slider, and changing the slider font on typography settings applies. However on the page for /builds, the slider font does not make any difference. Also, on the editor right pane, the image is referred to as the header image. It does not scale well nor provide much of service so I would like to know how to change the font and disable it entirely.
This would be very much appreciated! Thanks in advance!
