All weapons effected by the visual enchantments texture pack are oriented sideways instead of diagonally. (All normal weapons are fine.)

I ran across an issue post that described a similar issue with the weapons from MCD Weapons. It said that later versions fixed this, but that was 2 years ago and I'm playing the later versions. If it's any help I used a custom Curseforge profile instead of installing fabric myself.

Positioning and size can get adjusted with a resource pack, check out the readme.
Resourcepacks of mods or standalone have an impact too.
