The trade entry, exit, and profit values are recorded in the CSV file.

The log does not record trades. It just records the events during the simulation. It lists the asset price at the moment of entry and exit. The price at which you really bought and sold the asset is recorded in the CSV, and it's normally different due to Spread, Slippage, and Rollover. Look here for details: http://manual.zorro-trader.com/spread.htm.

The EUR 0.84 in your above example is the profit of that trade. Where values are rounded, 84 cents are displayed as $1 and 10.4 pips are displayed as 10p.

The "$" sign in the message window has nothing to do with US-Dollars, it just means money. What currency it is depends on the simulated broker account. The default account is a micro lot EUR account.
