Not able to apply Brawler's Flurry

[kweise]

Hi,

I have a Brawler (Wild Child), who just hit 2nd level. I see the Brawler's Flurry in the Brawler tab, but on the In-Play tab there is no option to apply it. Is this option on some other tab that I'm missing? This character fights unarmed, and I have the unarmed "1" box checked on the Weapons tab. On that tab, Unarmed Strike does show both "Melee: +6" and "Flurry: +4/+4". Any suggestions? Thanks!
