After several attempts I can't seem to get this trophy to pop after 10 Tetra Master wins. I've tried both ten wins from the same NPCs and one win from 10 different NPCs to no avail. Is this a bug or am I just doing something wrong?

* Oh, and on an unrelated note I'm going to request that the developers please remove the Hail To The King trophy for getting 1000 consecutive jumps in the jump rope minigame or at least change it to something more obtainable. It's the one glaring flaw in an otherwise great trophy list and I know I'm not the only one that feels this way.
