Enchant glint is white instead of purple, chests have weird textures and are sometimes transparent when playing without 1.14 "Default" Textures

I play Minecraft only with the "Programmer Art" pack. Today I started Minecraft, and I saw a chest with weird and transparent textures. The enchant glint was white, with a pretty weird animation. I tried changing my pack, but it only get fixed when playing with the 1.14 "Default" pack (Enchant glint is purple and chests are normal). But whenever I switch back to Programmer Art pack or any other pack, the glints are white again and the chests textures are glitched.
