Fortune 3 enchanted pickaxe no longer works in 1.16.0.55 Nether Beta.

I updated my minecraft windows 10 edition and joined the latest nether beta (1.16.0.55). I had a survival world which i started in 1.14.30 and i wanted to play it in the new beta so i made a backup and started the world. I got myself a brand new pickaxe enchanted with fortune 3 and i went to mine all of my diamonds ore. When i mined my first patch of diamonds. I was surprised that there were 5 diamonds in that patch and i got the exact 5 like fortune enchantment didn't worked. I thought it was coincidence but after mining 1 more patch of diamonds i got sure that this is a bug. After this i did some more experiments to make everything clear. I mined the every single ore (which duplicates with fortune) and still fortune didn't work. I also downloaded the survival world of a youtuber which was created back in 1.14.1 and tried it in that world still didn't work at all. Please fix this bug. Also i am not using any extra resource or behavior pack.
