Remove folder icon on widget

Hi

I have searched high and low about how to remove the folder at the end of the product categories widget. I have found code to remove before and tried changing that to reflect after but nothing is working.

I have identified that this is in fact coming from Font Awesome but can’t seem to find the source code to remove through my inspector.

Am trying to attach a screen shot of what it looks like.

If there is an easier way to do this with a navigation menu, I am happy with that also.

Hope to hear soon.
