For example, if a transaction A has 5 confirmations and spends the same input as a wallet transaction B, B will be reported as having -5 confirmations. If another wallet transaction C spends an output from B, it will also be reported as having -5 confirmations.
To detect conflicts with historical transactions in the chain a one-time -rescan may be needed. Unlike earlier versions, unconfirmed but non-conflicting transactions will never get a negative confirmation count. Previously, every wallet transaction stored a Merkle branch to prove its presence in blocks. When loading a 0. This can reduce the disk usage from currently around 60 GB to around 2 GB.
