Issues On Site After Standard Theme Upgrade Please

Hi All,

I have updated my shopper press theme to the latest standard version and found a few issues. Not sure if to mention all issues in one post or not sorry. The website logo area (which i have full website header image in) is out of sorts, the height is all wrong and no idea how or where to fix this please? https://automotivecarparts.com.au/

Also you can see in the grey area the sub menu is missing aside from the checkout cart icon showing up and of course the search box??

Content on front page is running to far into the right side of the site. I have this issue on another area of the site where it runs straight over the right hand side.

I also cannot find where to remove the background on the “H” tags nor how to increase the content font size.

Any help anyone can give to fix these issues would be VERY much appreciated.
