$SPDR S&P 500 ETF Trust(SPY)$

Is it just me, or does the app's calculation for the cost on your Trades tab seems... wrong? Let me give an example with my trades:

I first bought a $S&P500 ETF(SPY)$at $444, with comission of $2, so the cost was $446, as expected.

Then I bought another at $405, with commission of $1, then sold at $412 with commission of $1, getting a profit of (7 - 2 =) $5.

Now the cost reflected by Tiger app for my previous share is $406, which is odd as $446 - $5 = $441 should be the actual cost price. Did my $30 value from the previous share just vanished out of thin air? Does anyone else experience this as well?

This is an issue, cause if I didn't do my own calculation, I would think I have profitted as the Tiger app shows, and would have incurred a $30 lost in overall value, while believing I got a profit.

  Price difference from current market price vs price after profit
