Hey does anyone know why my character sometimes stops when falling off this ledge only sometimes when I hold the move left input down it just stops at this point every time for about a second even when I am adding the normal movement input value in Player->AddMovementInput does anyone know how to fix this thank you! 
(ignore the green box to the side of my character - its a trigger box + is set to overlap all)
Here is what my variables that have something to do with the problem are in my character movement component:
- MaxStepHeight = 45
- Can Walk Off Ledges = true
- Perch Radius Threshold = 8000 - changed this from 0 because character was not falling properly and taking two steps to fall
- Perch Additional Height = 40
- Ledge Check Threshold = 4
- Always Check Floor = true
- Use Flat Base for Floor Checks = false
Please can someone help me out, I have been at this for days now, thank you
