Fluid and Bucket Textures

I recently attempted to create a custom fluid. The fluid flows and it spawns in the right dimension. There also was an option to create a bucket item automatically. I ticked it and checked the bucket out in-game. The bucket shows up in the tab an when I right-click somewhere to place the fluid the fluid gets placed. But all the textures are missing. The texture for the fluid in the bucket as well as the fluid itself. (Note: In the dimension, the fluid is supposed to be the textures for the fluid work) I got all the textures for it in the mod. Do the textures (Fluid flowing, fluid still and bucket) need to be named a certain way or is the automatic bucket a bugged feature?
