Texture bug

Using the version of minecraft 1.13 pre3 with the textures developed by JAPPA (the last version released) the vines have lost the textures and are visualized with the typical missing texture in pink and black squares, but only if placed, in the chest they are normally visualized .
I enclose below the image of the jungle near my house and an image of the vines in the chest

Thanks for the help in advance.

P.S. I've already tried to put back the default textures and then put the updated textures back, and I've already tried to re-download them, but nothing has changed.
