I think you may be misunderstanding the content of the screenshot.
We don't show you who handled the flags you raised. The "answered 22 hours ago by Sandip Pal" text is the information about when the answer you flagged as not an answer was written and by whom. This contrasts with questions which read "asked [time period] ago by [username]" there are some examples of this on your spam flags list.
Not an answer flags are marked helpful when a moderator handles the flag and marks it helpful (which is what happened in this case) or when sufficient users review the answer as "recommend deletion" or "delete" in the Low Quality Posts review queue.
