How to fix bullets offsetting when aiming at a certain point on the screen?

I am having this problem with my bullets offsetting whenever I am to the right of the screen.

Here's the video of what I mean.

Can anyone please tell me how to fix this? Comment if you need me to supply some code.

Edit: It might be because I am aiming literally at the sky and it needs to reach the distance of where I am aiming at.
