Block not dropping and same time to break with any tool or with bare hands

[Arfatox]

Describe the bug
When breaking a slab with any tool, the block will not drop and it takes the same time with bare hand or with and effi 5 diamond pickaxe.
And with any other block, being a fence or a full block it will just not drop.

To Reproduce
Just place a slab and try to break it in survival and do the same with full blocks and walls.

Expected behavior
The block just breaks and nothing is dropped.

Screenshots
No ss needed i think.

Version (please complete the following information):

• Mod Version : 0.5.0 but another user said the same behaviours happened in his 1.20.1 game
• Fabric Version : 1.21.1 (0.16.2)
  I've tried using this mod on a server with friends that was running forge but it wont work for some reason and i sadly do not have a screenshot or anything to help you further.

Additional context
Don't think any context is needed.
