Error in the menu: items from different topics overlap

I purchased the BRIDGE template and selected Bridge Original for Business with WPBakery. I’ve already loaded all the information onto the website. The website is displaying an error in the menu; items from different topics are overlapping. I’m at level 3. Could you help me correct this problem, please?
