The Bug:

"minecraft.custom:minecraft.use_cauldron" incorrectly increases upon using water bottles to fill cauldrons.

The action of filling a cauldron through the use of a water bottle is currently tracked under "minecraft.custom:minecraft.use_cauldron", when it should instead be tracked under "minecraft.custom:minecraft.fill_cauldron". The reason for this is because you are filling a cauldron through the use of a water bottle and not actually using the cauldron.

It's important to note that "minecraft.custom:minecraft.use_cauldron" does not increase upon using a bucket of powder snow, lava, or water to fill a cauldron. This is the correct and expected behavior, as you are filling the cauldron and not using the cauldron.

An example of using a cauldron would be collecting powder snow, lava, or water from it, using either a bucket or a bottle.

Steps to Reproduce:

1. Create a scoreboard objective for tracking when you use a cauldron and set it to display on the sidebar by using the commands provided below.

   /scoreboard objectives add UseCauldron minecraft.custom:minecraft.use_cauldron

   /scoreboard objectives setdisplay sidebar UseCauldron
   

2. Fill a cauldron using a bucket of powder snow, lava, or water and take note of how the scoreboard correctly doesn't increase.
3. Fill a cauldron using a bottle of water.
4. Take note as to whether or not "minecraft.custom:minecraft.use_cauldron" incorrectly increases upon using water bottles to fill cauldrons.

Observed Behavior:

"minecraft.custom:minecraft.use_cauldron" incorrectly increases upon using water bottles to fill cauldrons.

Expected Behavior:

"minecraft.custom:minecraft.use_cauldron" would not increase upon using water bottles to fill cauldrons.
