Transactions Excel TotFees?

I was looking at some transactions in Excel that I downloaded from a sim.

Date Symbol Type Shares Price Amount TotFees Rank
2019-05-27 SAP:CN BUY 4,310.00 45.20000076 -195,092.92 -280.9168613 98.68

I have Commission set to $0.01/shr so why does TotFees not = 4310*0.01 = $43.10 Where does the 280.92 come from?

That column includes slippage costs.

That’s what I figured but wanted to confirm.
