Resource packs with higher-resolution particles show up incorrectly

When I play Minecraft, I use a specific resource pack. It contains a few higher-res textures, like particles, and this is not an issue on 1.8.9 and 1.12.2(the versions I play on). I looked at the default textures (in the versions jar for 1.12.2 and 18w15a) and saw that they were the same file. I have linked the resource pack I used, so anyone can check.
Example:
when i hit an entity, it shows part of the fishing rod texture

(UPDATE: added screenshot showing rain particles)
