Can't Swim Down in Roblox Studio Terrain Water

If this post is in the wrong category, please inform me so I can move it! This was the closest one I could find.

  1. What do you want to achieve?
    I want to be able to swim in terrain water normally.

  2. What is the issue?
    I can’t swim down at all in the terrain water, it’s also choppy when swimming along the surface. It’s like something is interfering, but there’s nothing there.

  3. What solutions have you tried so far?
    I looked all over Google and the DevForum, only found one unanswered post that wasn’t helpful.
