Issue with diamond generation.

I downloaded the 21w14a snapshot and something is wrong with diamond generation; there is a massive disparity in the ore distribution chart. I started mining and made 3 horizontal shafts, 3x3 wide, for over 100 blocks each. Not to mention the mining to get to level -59. I ended up with 21 Redstone blocks and 3 red stone dust. Diamond count was enough to make one sward, one pick axe, and 4 diamonds left over…Total of 9 diamonds, that’s it. Granted the chart isn’t a 1 for 1 exchange but still even if it were half, I still should have ended up with at least 10 blocks of diamonds. You need to amp up the diamonds way more than what it’s at or figure out why the diamonds aren't generating they way they should.
