A lot of people are having trouble selecting personality-based or character strengths or flaws for your characters. Being allergic to chocolate, while interesting, is not a character flaw, it is a condition, perhaps to be listed under 'Quirks/Interesting Facts', but certainly not under flaws. Also, species strengths and weaknesses are in the species info sheets and don't need to be recreated on the character sheets (if you want to be specific about what powers your character has access to, feel free to add it in as an extra prompt).
To help out, a list has been comprised here that includes certain characters strengths and flaws. While not being fully comprehensive, it is certainly an expansive list that should help you on your way when choosing flaws. The list has explanations in them describing the strength or flaw, so you can understand the various things it can mean.
