Dropdown animation effecting tabs

Hi. Hope someone can help.

I have an animation on my navbar dropdown (which I want) however it is also seems to be applying to my tabs within the menu also.

When you click any of the “tabs” (conversions, services, stock vehicles or media) within the dropdown it triggers an animation - which I do not want to happen.

Is there a way to stop it working on the tabs but continue to work on the main menu dropdown.

Hopefully this is a simple fix?

Thanks in advance.
