Apple Watch show incorrect elevation after getting wet without water lock

When I normally wash my hands with my watch on, everything is fine. However, when I wash my watch with Water Lock off (in the shower, when I have Water Lock enabled, this doesn't happen, so I assume it's related to Water Lock being off), the elevation goes completely haywire. Where I live, my elevation is normally around 20 feet (which is what my watch usually tells me), but when this happens it can go down to -900ft or up to 900ft! Maybe this is related to water interacting with the barometer, but I don't know. I have washed my watch probably around 50-ish times since I got it, and right now and last night were the only times this has happened.
