Poveglia theme errors

Is anyone using the poveglia theme? And if so have you made submenus with this theme. My website designer is having trouble with creating submenus that fit this theme. It doesn’t look right. The newsletter is also messed up, and not in the right areas. And also with adding the contact form. Please help if you have resolved this issue. I don’t know what to do.

Did you make the submenu works?

The submenu does not look good with the theme. I am putting customization on hold till I can find someone to fix theme errors.
