This is normal, albeit upsetting. Your account is sometimes credited for clicks that are not valid. Example a user clicks twice on the same ad or similar situations. After the system detects the error your account is adjusted downward accordingly. Note the earnings reported in your account are "estimated" earnings and thus subject to change change and adjustment.

The other adjustment that cause considerable grief for publishers is the "clawback" that often occurs when the "estimated earnings" are converted to "finalized earnings" or "balance". These clawbacks are the results of invalid clicks and are documented in the payment section of your account.
