During our latest sessions one the players (Human Champion Fighter) leveled up to lvl 6. When he tried to select a new feat though he only had one option (see screenshot).

Am I missing some rule here or is this a bug?

Thanks!

 Edit: I have purchased the PHB and shared it with all of the players in the campaign

Hi filcat,

Thanks for your reply but I have purchased the PHB and I still only have one option available.
