The sum of 3.569,14 € is the difference between 3.569,14 € which you earned in total and 2.140,18€ you already have been paid.
"Übertragungen" always displays, what you already have been paid.
"Einnahmen" is your total income
"Ausgaben" are your expenditures
Everything you earned between May 5th to May 19th has been paid out on the 19th of May. So basically, everything you earn in a 2 weeks disbursement cycle, you are paid at the end of this cycle. So if what you earned after the 19th will/was paid out on the 2nd of June.
