Click BUILD -> Feats
Look very very closely at your list of feats under "Feat Choice Checklist." near the bottom 1/3 of the window. You should see a little "house" icon in gold next to "All choices made" (It won't say all choices made if you currently have unused feats). Click this to add a feat. I sometimes have some random bugs with house rule feats not counting as prereqs for feats, but of course, you could just house rule those feats in too.
