App / Cloud sync is breaking balances

I don’t know why. All balances changed. Year to Date transactions are in order. I have 4 years of data. So I won’t be searching what’s changed. First it was the difference in numbers between 2 devices. I’ve cleaned up iCloud. Made a regular backup file prior where things are in order. Deleted app from all devices. Reinstalled app and restored it with that file. Manually turned on iCloud sync via settings. Two weeks later again broken numbers. Insane
