Liquid Area Sound Continues

[dailycreepypasta]

For some reason, on only one of my maps I go into an area with a liquid area and for some reason when I get out of it, the sound of walking in the water continues until you get killed. For example, I would go into a liquid area, go up a ladder area and walk around the level making the water sound when I walk. I checked the size of the liquid area and it's making the sound even when the player is outside of the area. Has anyone experienced this and is there a way I can fix it? If it helps I'm using Amnesia: TDD v1.3 and the HPL Editor Suite that I downloaded for version 1.3 about 3 or 4 days ago.
