Hi,
I think I found a bug. I was editing an ETH transaction (imported from CSV from Bittrex).
I edited sent amount from 0,1049514 to 0,1109514 (i have to add transaction’s fees, they are not exported in CSV) but when I click save, amount went to 0,1169514 ETH.
Basically, somehow, the fee I added was added twice!
It happened again with another transaction of the same type (ETH from Bittrex to another exchange)
Hope it helps to fix it.
