Ok... once again... one of the coins you are trying to spend is UNCONFIRMED... and the transaction creating it does not appear to have propagated well... this missing transaction with the missing coin has a fee of 1 sat/byte... hence why it hasn't confirmed and seems to have been dropped by most of the network.

Your current transaction with the large size and the 71 sat/byte fee CANNOT be confirmed until this missing transaction is confirmed.

At this stage, your best bet is to just wait until ALL your transactions are dropped... "abandon transaction" and/or zapwallettxes and then start all over again.
