Fixed Water acts like a blob of gel and craft get stuck, no buoyancy

Synopsis: A craft landing in water sinks down a few meters and then stops moving completely as if stuck in a giant "blob of gel". Switching altitude modes shows incorrect values.

Reproducible: Yes, tried several times, always the same result.

Test scenario:

• Simple craft: Mk1 pod, small heat shield, small stack separator (yes, for fun I used this instead of a decoupler), Hammer solid rocket motor
• Flight path: Launch from pad, turn towards the ocean, angle does not matter
• After Hammer engine runs out stage via space and let the pod fly on its own
• Switch SAS to retrograde, when velocity is reasonably low stage parachute via space bar
• Parachute opens and pod glides down slowly as expected
• Touchdown on water with about 6 - 7 m/s velocity (no timewarp enabled)
• Pod sinks about 9 - 10 meters deep into the water and then does not move anymore, no buoyancy at all

2 Screenshots:

• Craft landed and under water (it does not move or bobble, it is stuck in position), Altitude above Sea level = -9 meters so it sank down a bit before being stuck
• Same scene, click on the altitude mode button to switch to AGL (Altitude above ground level) -> Expectation: the same as sea level -> Result: It displays 327 meters AGL which can't be correct. The AGL was correct while flying, it slowly descended to 0 while I was on parachute, just after landing it shows 327 meters all of a sudden

Edit: It seems only one picture got uploaded, the first one is missing, it is exactly the same but the altitude reads -9 meters and it is with mode "above sea level".

Edit 2: After some more testing I can say with high confidence that the "327 meters" bug only happens with the MK1 pod (100% of the time with that). Larger pods do NOT show this problem and display 0 meters in both AGL and ASL after landing. But they also feel like "stuck in gel" as they are not moving around and stand upright in the water.
