I'm seeing a lot of conflicted and/or orphan transactions as a result of staking but not winning those blocks. Is there a way to clean them up and not show them? I don't like seeing them.
Yes, there is a simple way and it doesn't (or shouldn't) affect your coin balance.
1) Backup your wallet if you haven't done so recently. (this is just a precaution and not mandatory)
2) In your Qt wallet, go to Tools -> Wallet Repair
3) Run the Recover Transactions 1 (zapwallettxes=1)
It will now go through your wallet and scrub out the orphan transaction. Should take few minutes.
