Articuno SV # 16 is placed in the "hit the bench" column while it cannot.
Zapdos SV# 48 has this same problem.
This is a very handy feature, Im very glad that its on pokegym.
One thing that maybe you could add though is instead of just a hitting bench catagory, you could also do a "spread" catagory for guys that hit multiple, or all, of your opponents benched pokemon.
