update now logo shows up twice in header

I just updated my Highend Theme. And my logo now appears twice in the header. 5.4.2 version. It was fine before the update. I’ve tried changing the header style but then there are other problems. Not all of the navigation bars appear when I change the header style. And I am using the side navigation header choice when I see the two logos. I’m able to just get one logo on the top bar navigation choices, however, not all of the drop down navigation bars work. Please if you could give me some advice. It was fine before the update. Thank you. April Thompson
