Steps to Reproduce:

1. Place a Sculk Sensor on the ground;
2. Use a comparator to get the correct signal type;
3. Place a redstone dust line in front of it to observe the signal strength;
4. Place a fluid (water, lava) and observe its signal strength;
5. Remove it and observe the redstone again.

Observed Results:
Placing the fluid produces a level 13 "Fluid Pickup" signal and removing it produces a level 12 "Fluid Place" signal.

Expected Results:
Placing the fluid produces a level 12 "Fluid Place" signal and removing it produces a level 13 "Fluid Pickup" signal.

Notes: I originally thought the signal strengths were reversed, but upon noticing something I no longer assume that's the case. I realized that the powder snow bucket is no longer affected by MCPE-115444 when being placed down, but the same behavior can still be observed when it's picked up.
