Strange Round Robin problem

[RestrainT]

Hi, when I make a keymap for a keystroke, and use the "Round-robin within selected Target" function, its not working correctly. When i press the key the round-robin works as intened for my 4 characters, but when i start pressing it again its not working for the first 3 keystrokes, then it works again. Like this:

How i want to to work:

1 time Press F: Toon 1 Presses F
2 time Press F: Toon 2 Presses F
3 time Press F: Toon 3 Presses F
4 time Press F: Toon 4 Presses F

What i got now:

1 time Press F: Nothing happends
2 time Press F: Nothing happends
3 time Press F: Nothing happends
4 time Press F: Toon 1 Presses F
1 time Press F: Toon 2 Presses F
2 time Press F: Toon 3 Presses F
3 time Press F: Toon 4 Presses F
