So I checked the support and get the following answer:
"It seems there is a conflict with the main-menu position of this template. You need to create different module position in the top bar to make DJ-MegaMenu work properly. Templates often has dedicated positions for standard joomla menu where some script manipulate the menu elements and probably this is what happens in this case.
You can ask your template provider how you can use different menu module in this position in the way that template script will not mess it up."
What should I do or how I should proceed to resolve this conflict?
