[GAME CLIENT] 'Player Attack Move Click' does not work until binding created per game.

I have the 'Player Attack Move Click' binding set to 'Ctrl+MB2'. It does not work at all in the game until I create a new binding in some way. I can confirm that this happens every game for at least myself. Steps following.

1. Load game with bindings preset: Player Attack Move Click - Set 1 - Ctrl+MB2 Set 2 -

2. Walk near enemy minions using 'Ctrl+MB2'. You will walk normally, not attacking.

3. Change bindings to the following: (Just swapping the current binding onto Set 2) Player Attack Move Click - Set 1 -
   Set 2 - Ctrl+MB2

4. Walk near enemy minions using 'Ctrl+MB2'. You will attack-move as expected.
