List Icons also showing other other icon

Hello

I’m trying to insert a basic list. I chose a tick icon to use for the list and on preview its fine.

When I actually save the shortcode on my page I get not just the green tick icon but also a black arrow just next to the green tick

I checked the source code and i get this as an example line of one of the list
