This question already has an answer here:
I know this question has appeared several times, but as I do not find a proper explanation I want to show my case:
- I suggested an edit on tag alias excerpt because there was a typo.
- The edit was approved by two users
- Community user rejected it
- Another user edited what I had suggested
- I got a "rejected" message
