Third person character does not provide velocity in the z direction

The Velocity in the Z direction does not change (unless the character jumps) when using "Get Velocity" on the character from the third person template.

1. Created a new Blueprint Third Person project
2. Searched the Content Browser for "ThirdPersonCharacter"
3. Double clicked "ThirdPersonCharacter" BP Class to open
4. Right clicked in the Event Graph and searched "Event Tick" and added the Event Tick node
5. Right clicked in the Event Graph and searched "Get Velocity" and added this node
6. Right clicked in the Event Graph and searched "Print String" and added this node
7. Connected the exec of the Event Tick to the Print String exec
8. Connected the Get Velocity "Return Value" to the Print String "In String" (conversion will be auto added)
9. Compiled and saved the BP
10. PIE
11. Moved up and down the stairs and then jumped

Result: The Velocity in the Z direction does not change (unless the character jumps)
Expected: The velocity in the Z direction would change as the character walks up and down the steps

[Bug Report] using 'GetVelocity' node, does not give any value along 'Z' axis while running on bumpy surfaces
