The face and feet of sheep missing when I use Plastic Texture Pack

Today , when I bought Plastic Texture Pack in Minecraft Windows 10 Edition , I found out that both the face and feet of a sheep are missing when I use the texture pack . It literally looks like a sheep-like wool to me . I hope that Mojang can fix this problem as soon as possible , obviously under your capability of doing things because I know that there are thousands upon thousands of bugs reported every day .
