Custom projectile collision issue (bounding box) - MCreator 2024.4

I made a custom projectile with the following : https://prnt.sc/zMKmtsOejiEh

I noticed that in the game, custom projectiles hit entities below them regardless of the distance. However, this does not happen if the entities are above, to the right, or to the left. It also does not occur if I use arrows as the base projectile, therefore it's certified as a custom projectile issue, perhaps the new feature with the boundy box.

I'm launching the projectile using a keybind that triggers this procedure : https://prnt.sc/SzSca288llrE 

Here is what happens in the game : https://prnt.sc/_s7-pW4rsyWf / https://prnt.sc/pIL4JPjOSDum 

Tried it with both Neo Forge 1.21.1 and Forge 1.20.1 (MCreator 2024.4)
