Copper and Osmium Textures are not showing up

I am Using this on MC Eternal modpack 1.12.x and for some reason Copper and Osmium are giving the magenta/ black checkered textures. Not sure how to fix this so thought I might post it here

If someone can let me know how to add the textures myself I don't mind doing it but I am pretty new at this stuff. Also Just found out that there are a few others not showing up also...could be lead and silver but will double check and update it once I am sure.
