Am I interpreting it right? As in I have participated in 1 bounty? Or
is this a grammar error?
In that specific area, it states " bounties" and not " bounty" because the word "bounties" is a fixed name to identify the profile area you can go to which is all about "bounties".
And the  is just a system indication of the number of "bounties" you ...
You posted an answer there, before starting bounty:
Note: If you are offering a bounty on a question that you have already posted an answer to, your minimum spend is 100 reputation (not 50).
