Here is a wallet that I’ve just reimported again using CSV in order to make things more organised. It had the same problem before I did this when I had just manually added in each transaction.
The remaining balance math doesn’t make sense. However, it is correct on the Wallet page:
I’ve seen this fault in regards to other wallets I have too, however this is the first time I’ve noticed that the wallet page math is working correctly and that perhaps the issue is only related to the mouse-over “i” facility?
