Subhzash,
It could be that your are running several keywords where at least 2 of them are similar, e.g. dancing clothes & dancing outfits, both displaying the same ad. One of them (say dancing clothes,) would not be showing (and has no average rank in the c.panel,) because the editorial team rejected it or the bid was too low.
If this was the case, you would be seeing your other keyword / ad online appearing when you type "dancing clothes" because it still contains "dancing" in it and you think it is your other non-validated ad which is showing.
I hope my explanation is not too confusing, it's still early in the morning, i get better as the day matures...
