Nether Quartz doesn't affected by fortune enchantment

I was getting some quartz for a project, and when i focus at me mining with my fortune pickaxe, it doesn't seem to increase or something. I searched in wiki that the quartz should have affected by the fortune enchantment. I'll give a video link for it (because the video size is 90MB+ , cant upload it here) : https://youtu.be/KCTbjpGpn2I
