Sprintscript prevents zooming with the sniper rifle

As you can see from the picture, the sprint script somehow interferes with sensible aiming with the sniper rifle. Without the script the aiming works as it should. Unfortunately, I have no idea how to fix this error, since I know very little about scripts. I hope you can help me! Thanks in advance.

I also have the problem that the water does not react to the player (splash sounds & underwater sounds).
