Jumping after walking off a ledge does not allow for Max number of jumps

If the max number of jumps is 'n', jumping from the ground allows for 'n' jumps, but walking off a ledge and then jumping only allows for 'n-1' jumps.

Ex:
If Jump Max Count is set to 3 (triple jump), walking off a ledge only allows for two jumps.

1. Open UE4 Editor (Third Person Template)
2. Open ThirdPersonCharacter blueprint
3. In class defaults, search for "Jump" and set Jump Max Count to 2
4. PIE
5. Walk up the stairs and walk off the ledge
6. While still in the air, press the jump button twice

Result:
Character will only jump once

Double Jump does not work when walking off ledge
