Quartz blocks glitchy

In survival mode, I collected nether quartz and went to my stone-cutter to craft it. The problem is, whatever quartz block I craft, it claims I have the same number of the others (possibly an identity glitch). I couldn't craft pillars except for two at a time, and any slabs I craft draws from both chiseled, pillar and regular quartz blocks.

No mods, no jailbreak, purchased most recent version from the app store, most recent iOS software on a iPhone 5c 16gb.

This is my first post of a problem, please let me know if I can improve or be more specific Hope this helps others with the same problem.
