Yes that TX never happened, that is why it does not show up on the explorer page. The 000 is no sign of a failes, but on top the 0 confirmations are.
I guess your status is now, that these are missing in your wallet. If it is like that, please open the debug window inside the wallet and run the command:
repairwallet
That should find these coins and add them to your wallet again.
This can happen, when you are active staking and try to send a block that is getting a stake. So the wallet trys to send it, but it not avaiable due status "in stake"
I hope this helps you.
Thanks Shahim,
I just did repairwallet and it's all back
