The bug
Some blocks do not cull the faces of the same block if it is placed next to them, making large areas of this block appear as tiles.

Fences have lot of non visible faces rendered too, model is ok, in code shouldRenderFace = {render true} just remove it and it's ok
Or just remove the texture assigning, like in MC-114779, else you'll limit resource packs.
The bottom should not be removed
For the side I don't know if the fence can stick to a non full/opaque cube, but maybe they can be removed
@unknown that's MC-109087.
