Wind Charge bug with blast prot 4 armor

So I was playing on 1.21 snapshot and i created a world and i put blast prot 4 on all my netherite armor and when i used a wind charge without pressing space i didnt go up in the air AT ALL and when i used a wind charge With spacebar still in my blast prot 4 armor i only went up 1 or 2 blocks in the air. The same thing happened again just with a mace and wind burst 3 enchantment the mace didnt even launch me in the air, rather it just acted like a regular mace with any enchantment BUT windburst. Is this a feature or a bug? Im geussing a bug. Plz fix before 1.21 fully releases. I'd rather the release gets DELAYED for like a day or 2.
