Sprint in water inconsistent/nauseating

When sprinting in water while floating (holding A to float and left stick toggle for sprint) the speed becomes that of sprinting only while floating up, and acts as if there’s no sprint when floating up. The zoom in and out makes it very difficult to look at the screen and I cannot effectively move in water. I understand there was a bug fix for float sprinting being faster than underwater swimming, but I believe this inconsistent speed is also a bug and should be fixed.
