Bitcoin transaction not confirmed 5 hours

How much did you pay in fees? when they are too low, it takes a while to confirm.

Keep in mind that you will not lose your coins. The fax will either be confirmed or approximately 48 hours if it has not been confirmed that it will be invalidated (your parts will be returned).

Some portfolios report that a utxo is only used after a transaction using it has been released and confirmed. As you have no confirmation, it is probably why it is marked as unspent
