Hello,

1. Update the theme and all the plugins related to the theme.

2. Then rearrange your category menu: add main items: http://prntscr.com/lfvn2x

3. Create HTML block for each main item.

4. Then choose and set it in each main item: http://prntscr.com/lfvnwp as you see you need to configure “set size” to see the HTML blocks dropdown

Here is the reason why other menu items are different from bio and imperesson http://prntscr.com/lfvpef
