Wrong placed and positioned items in frames

I´m currently making a resource pack with 64x64 resolution/quality, and i see there's an item not scaling and placing properly, the item has the texture called "double_plant_grass_carried", and recently i notice there are another textures doing the same, kind of, only the grass one scale up (at the moment, i hope) and the rest is small, . I've tried swaping textures with anything else, checking the .json files and editing them, made the resource pack from scratch, but the bug is still there.

After doing some research i couldn´t found a certain answer, and the same issue was reported by a phone user, but the staff answered him there was not solution yet.
