Not a Schwab error. All brokers do it. Any after hours t trade is annotated as the last price in calculating account balances. ETrade does the same thing. Nothing to worry about. 1st trade tomorrow during market hours will correct which is not really a problem.
The trade posted after hours, but was made sometime during the day. My Etrade acct shows same thing. Relax, this will open at .0146 or higher tomorrow.
