This is not a bug, it's working as intended.I just came across a bug in leveling monks up. If you already have Combat Reflexes and don't qualify for Deflect Arrows you can't select a 2nd level monk bonus feat and thus can't advance to monk level 2.
This is a bug for two reasons. First and foremost it prevents you from leveling up your character. Secondly, a monk isn't supposed to need to meet the prerequisites for their class bonus feats (see https://www.d20srd.org/srd/classes/monk.htm#bonusFeat)
It's the developer's way to tell you that you shouldn't play a fucking monk.
