Hi, I updated to Version 2021_2_5 made some slight changes and republished my website.

When I look at it in "Preview" it looks perfect but when I publish it the background colour is missing behind the menu buttons on the side bar and it looks terrible! I've tried changing colour, repositioning the buttons ans making the background og the buttons transparent but no matter what I do it will not display correctly on the published website. See the two attached photos to see the difference. Any help would be appreciated. :)
