Author, can you tell me what mods this resource pack requires to work properly without using Optifine? Without this information, I won't be able to use the binary search method to pinpoint the possible culprit mod, as I might accidentally remove the resource pack's dependencies during the process. I have way too many mods.

There aren't any dependancies, although it can work with polytone for more support with mods, in this case the mod that's causing the issue is whatever is naming the villagers

Thank you for helping me troubleshoot. After conducting tests, I would like to provide feedback on the actual issue I intended to report. Previously, this issue was obscured by the earlier problem, making it difficult to identify the cause:
Your resource pack does not function properly on specific villagers. These particular villagers differ from others in that they are converted from cured zombie villagers. As shown in the images, the first picture depicts a naturally spawned villager, while the second shows a cured villager. Even though both are named, they exhibit different behaviors.

(Allow me to ask one more question: Regarding the conflict with the mod that names villagers, is the issue with your resource pack or the mod? If it is with the mod, I will submit an issue to the author's GitHub.)

Regarding the name issue, it's less of a mod/pack issue and more just an incompatibility with how the systems are defined, i have fallback systems in place for modded things but they're not 100% yet

regarding cured villager, i have some questions, namely:

what version is it? i assume 1.20.1
do you actively have the ui open or are you looking at the villager?
can you show how it looks in vanilla?, i'm looking for any sprite that might've slipped the cracks and is rendering in front of everything.

1. Minecraft1.20.1、Forge 47.3.33
2. I'm opening the UI. However, you reminded me of something: the Provi's Health Bars mod displays the trading UI you created in the top left corner when the crosshair points at a villager, which is why I removed it and replaced it with another Health Bar mod.
3. I am indeed using other resource packs, but yours is placed at the top of the list. Below are two images you might need, one with only your resource pack removed, and the second with all resource packs removed.

that last image is a converted zombie villager?, i want to see the differences between the 2

This is clearly a cured zombie villager. If it were a villager that hadn't undergone the curing process repeatedly, it wouldn't be possible for him to sell an enchanted book, which normally costs 30 emeralds, for just 1 emerald.
I'm not very proficient in English and I'm currently using translation software. What differences are you looking to see? Are you referring to the differences between a naturally spawned villager without any resource packs and a cured zombie villager also without any resource packs?

I apologize i completely forgot how the game works lmao.

I believe this is due to the discount strikethrough rendering on top of everything i'll look into it

Which mod you use for making hand small?

This mod, named "Yes Steve Model," is built around GeckoLib and allows players to replace their character models with custom ones. If you look closely, you'll notice that my actual model is displayed in the bottom left corner. The hands of this model appear quite small due to their realistic proportions. The mod comes with several free models, but if you want a model like mine, you'll need to sponsor the designated creator.
