Textures on customized block mannequin are glitched out when in-game, however seem accurately in Blockbench. How can I repair this?

I'm new to modding and needed to start out studying Hytale modding, so I'm new to Blockbench as effectively.

My texture is a modified blackwood planks texture from vanilla, and it's 32×32. The railing mannequin is simply 2 cubes. Every little thing within the asset editor appears to be appropriate as effectively. I'm unsure what to do about this one. UV mapping needs to be high quality from what I can inform.
