Pointed Dripstones are not working on Cauldron with 1 layer potion to be filled up.

Pointed Dripstones are not working on Cauldron with 1 layer potion to be filled up. This happened after I created a new survive world in the updated version, previously still worked, but there is no longer working on the filling layer. I also tried to test it in Creator mode, I placed 100 cauldron, some without potion (water is filled up by pointed dripstone, except potion) and i waited 3 hours, those Cauldron with potion are not filled up. So, it still doesn't work.

**This happen after updated version
