I believe adapt is being counted in # of spells within CMC distribution bar chart.

Note, i have 2 realmwalkers and 3 shaman of the pack, for 5 cmc3 spells.
The CMC distribution bar chart shows 9 spells at CMC3, which is incorrect.

The only way I could account for this was if the 4 adapt from Growth-Chamber Guardian was counting toward CMC3 spells.
