Hi Kendalyn83,
Thanks for coming to Apple Support Communities for help today with the arrows you see in Location Services.
The arrows mean that location services have been used for that app or feature. Find My is an app the can be used to share your location and find your iPhone. It's possible the arrows are there because they were both being used recently.
You should see an explanation of the three types of arrows at the bottom of Location Services.
A hollow arrow means that an item may receive your location under certain conditions. A solid purple arrow means the item has recently used your location. A gray arrow indicates your location has been used in the last 24 hours.

Have a fantastic day!
