Updated and clearer description from MCPE-139668
On Java Edition, the dripstone caves can generate more dripstones on the ground and on the ceilings. However, on Bedrock Edition, they generate way less, or mostly even lacking those, making the dripstone caves far less challenging to traverse and more barren with just the clusters generating in the middle of it.

Step to Reproduce
1. Create a new world with caves & cliffs experimental toggle on.
2. Find any dripstone caves
3. Compare it with Java's dripstone caves.

Expected Results
They generate the same way.

Observed Results
Dripstone caves on Bedrock lack dripstones on the ground and on the ceilings.

Original Description
If a Player were to compare the Dripstone Cave Generation on Java and Bedrock the Player can tell that the Bedrock Dripstone Caves lack the Dripstone Block Pillars and Dripstone Block Pillars with Pointed Dripstone. Furthermore Dripstone Caves on Bedrock Lack the Proper shape in the caves which is air in a circular formation surrounding each pillar. Features of Dripstone Caves Generate Far Less on Bedrock Than Java.
