Why there’s more loss then it’s should be?

Hi T212 team & Community,
@Team212 @George

as I’m new to T212, just bought 3 different stocks yesterday( BAC, T, UMC)
As you can see below on all 3 screenshots, there’s average price(which I bought) and selling price, difference In calculation in my loss is more then it’s should be??

In BAC, loss should be -$0.40, But it’s -$0.50

In UMC, it should be 0.00, But it’s -$0.20

And
In T, it’s should be -$0.10, but it’s -$0.15 ??

Am I missing/understanding something wrong here?? Or it’s app is counting wrong with some bug maybe??

Please help me team…!??

Thank you…
