Caret-down or down arrow not showing when navigation has submenus

[labanino]

Not sure if it is an issue but the thing is that foundation by default shows the down arrow when there is a submenu. So, I pasted the navigation's code generated by Wordpress in jsfiddle and it shows the arrow. Question, I know many people doesn't like this arrow so, did change something on the css of js for the arrow not to show? Thanks.

It is removed in the _navigation.scss file. You can edit this file to your taste.
.dropdown.menu:first-child > li.is-dropdown-submenu-parent > a::after { display: none; }

What's up with :first-child? Originally is:
.dropdown.menu > li.is-dropdown-submenu-parent > a::after {}
Anyways, thank you very much @dantahoua !
