When running multiple clients in PIE the second player's inputs become toggled every tick when setting Input mode Game only on tick

A user has found that setting input mode to game only on tick will cause the client in PIE to toggle their inputs on and off every tick. If this test is run with a single player the inputs are constant and do not toggle. However when running multiple players the client's inputs toggle on and off.

Note: This is show by using the command "Showdebug INPUT" and the inputs are 1 when held and 0 when not being held.

1. Open Editor
2. Open the level blueprint
3. Set the input mode to Game only via a tick event
   Tick Event > Get player controller > Set input mode Game Only
4. Change the PIE setting to 2 players
5. Play in Editor
6. Select the Client window
7. Bring up the command line using the '~' key
8. Put in the command "ShowdebugINPUT" via the command line
9. Press the 'W' key to walk forward
10. Notice that the Input is flashing between 0 and 1
11. Exit PIE
12. Change the player numbers to 1
13. Play in Editor
14. Bring up the command line using the '~' key
15. Put in the command "ShowdebugINPUT" via the command line
16. Press the 'W' key to walk forward
17. Notice that the Inputs do not flash (Expected)

Expected: Inputs do not toggle for the clients when setting the input mode
Result: Inputs toggle on and off for clients when setting the input mode
