On hover background color problem

Hello,

I have purchased your product and it's amazing,

But I have a problem customizing the background colors when the item of the menu it's on hover.

I changed the background-color of the menu to customize it, but when the element is on hover,
for a moment the background-color have the desired color, but it automatically changes to the default on-hover color.

It happens in the level 0 megamenu, and in all the childs with a white-gray.

It's possible that has some javascript in action?

And if it's this case, there's some way to change it?

Thanks in advance.
