Why cash out amount is 90?

[8m0]

Hi, i am trying to figure cash out button functionality, for that, i make some bets to understand math under it. Today i got confused with the situation on screenshot.

So bets look like so:
SU:
Back 3.05 - 2.00$
MA:
Back 1.75 - 2.00$
Back 1.58 - 2.00$
Lay 1.78 - 2.00$

Until that moment i would suppose it should be ~0 for cash out amount, but how is it 90?
