Mari's Secret Shop not giving the right amount when purchased

I purchased a bunch of materials with blue crystals on Mari’s Shop and when i collected them i noticed i was not getting the proper amounts. I purchased 2 Life Leapstone (Bound) [10] for 14 Blue crystals each, when i put them in my bag after claiming them it came out to 10 total. Is this a bug you are aware of? I know its small but i would like the items i paid for.

just had the same experience. It’s ridiculous there’s no history of purchases to confirm it…
