When underwater with the SOAR underwater Weapon, you are able to move forward and faster forward while Aiming Down the Sights (ADS), while in 1st person this will result the players view position being placed at the back of the Weapon and the view position when moving fast forward is placed at the side of the Player Character model near the right hip resulting in incorrect camera position which is quite ugly.

This is issue could be corrected by maybe disabling the ability to Aim Down the Sights while moving fast underwater.
