What can be done with a transaction with 0 confirmations, in memory pool but I've already double spent to complete a payment request.  Will the original amount of bitcoin be returned to my core wallet?  How can I clear the unconfirmed transaction from my core wallet? My wallet shows two different amount balances, one of which is a pending.  However; the pending and total is less than the difference of the two transactions (first sent with too low of fee, and then the double spend with a higher fee).  its off by about 0.01 BTC.  Any suggestions... or is it just a waiting game to clear the transaction from mempool and then my wallet balance will go back to normal.
