Those 84 suggested edits that were accepted includes the suggested edits for posts that has been then deleted. If you look at http://drupal.stackexchange.com/users/12418/bala?tab=activity&sort=suggestions, you will notice it says you have 95 suggested edits, not 110 (84 + 26).

Since you loses the reputation gained from suggested edits when the post is delete, I get that those suggested edits are not even counted to get the badge. See your reputation where it shows something similar to the following.

If you don't get the badge, I take that is the reason. Otherwise, it's only a delay in getting it, since cron tasks that check who gained badges run at different times. Some checks are done more frequently than others; it all depends on their computational cost.
