Canasta is flawed

In Canasta, red 3s are worth 100 points. You add 100 points only if you have secured it/the, with a Canasta. If the red 3s have not been secured by a Canasta, they are to be deducted from the players score. This app adds 100 points per red 3 whether or not they have been secured by a Canasta. There are other logic flaws as well, but this one stands out.
