Primary Menu text issues.

Hi,

I followed the tutorial supplied on your website (https://docs.themeisle.com/article/320-how-to-increase-zerif-logo-size) on how to increase the header and logo size. However, now the text is no longer horizontally centered. See this image: https://pasteboard.co/cpfDDHX6J.png
Is there some CSS that could fix this?

Thanks in advance!
