and

Withdrawal: 50

After accidentially deleting the first one, i connected via AqBanking to my bank account in order to obtain it again. I expected that the matching procedure would recognize that the first transaction is missing and insert it again. However, it matched the first transaction with the still existing second transaction, although there are not too many similarities. It also matched the second transaction with itself, so this is not really a matching in the mathematical sense. I think that the matching procedure should recognize that the first transaction does not exist any more and recreate it. Maybe it should ask the user in doubt.
