How to remove the indicator only below the main menu item, which has a sub-menu?

Hello,
I have an orange indicator below the main menu items. The indicator is active also when current page is selected.
But how can I remove this indicator only below the menu item, which has sub-menu? If you look at my site the menu item, for which I would like to remove the indicators are: About us, Solutions. The indicator is displayed when moving down to the sub-menu.
My site:

And this is the effect, which I want to achieve: https://www.eurocontrol.int/
There is no indicator just below the menu item “WHAT WE DO”.

Can you help me to achieve the same effect?

And if possible, I would like to ask how could I put the same arrow to the right of the item (WHAT WE DO) that rotates 180 degrees on hover state?
In my site I have placed the arrows next to the menu items which have sub-menus as I have pasted a Shortcode after the menu item name in the Appearance/Menu from the Dashboard.

I really hope that you can help as always.
Thank you.
Galina
