Can't Do Left Shift + Direction While Jumping

Please don’t bump questions that are unanswered less than 4 days. (:

Since i don’t have something to do right now, would you mind showing me your Blueprints? Then i can check if you did something wrong somewhere.

Also i need your Key Setup from the project settings.

Maybe i can find something, but it sounds really odd that you just need to change it to control and it works.
