you already sent it with a very low fee a hours ago,
and you 'repaired' it back again then trying to send it once again,
but it's failed or error ?
of course it will because your transaction has been processed,
and you should know how long it will takes a time based on your fee transaction,
look here for more information about transaction fee times :
https://bitcoinfees.21.co/if you really used a 'very low' fee, i am afraid you will get it in a few days later.
because it's very busy right now and your will shows 0 actually even if you 'repaired' it back
