The martial arts bonus attack states it specifically excludes weapons you have to wield with 2 hands. The quarterstaff isn't a 2 handed weapon normally, but you can make it a 2 handed weapon by using the versatile feature. Therefore, when using a 2 handed weapon, you aren't able to use the martial arts bonus attack.
I don't see where it says that.
Please provide the quote and page number.
This is what I see:
"When you use the Attack action with an unarmed strike or a monk weapon on your turn, you can make one unarmed strike as a bonus action."
