Weird textures on blocks

[Charlescourn]

i just downloaded the PureBDcraft 512x MC114 or version 1.14 and I noticed right away that the stone brick had different textures on it than what it should same with the dirt. I thought it was weird so I went into creative mode to check it out and low and behold other blocks had the same thing, oak log, diorite, diorite stairs, diorite slab, podzol, lime wool, lime carpet, jack o'lantern, and packed ice. the thing is that from a distance they look fine but when you get close to them the "bug" appears, but for some blocks, like the dirt and the stone brick, it doesn't appear on all of them. I don't know what this is I just want to know if we can get this fixed cause it makes my house look bad and its annoying XD
