Lost 17 Shares after Sale Order did not fill

On July 6, my paper account held a position that was confirmed by the position API. My software, submitted a limit sell order for 17 shares, but the order expired unfilled at market close. There was no filled sell order, liquidation, or account activity showing those shares being removed. On July 7, the position API reported a lower share count, and the missing 17 shares were gone without any matching transaction in the activity history. The order/fill history and the reported position no longer reconciled, which suggests the paper account position state was lost or corrupted overnight.

Alpaca Team can you please return the 17 shares to my paper account and can you please confirm this will never happen with a real account? I am getting ready to start a real account using the Alpaca’s API and this is somewhat scary.
