How do I add the same stock into 2 different portfolios?

Within Seeking Alpha, I have 2 portfolios.  I have 1 specific stock that must be in both portfolios.  However, if I input the shares and price per share in Portfolio #1, then the same shares and price, for that stock, appear in Portfolio #2.

For example:

Portfolio #1:  I input 20 shares of XYZ at $2.00 per share.

Then I go to Portfolio #2 to input 30 shares of XYX at $2.25 per share but I can't.  The XYZ stock data from Portfolio #1 is automatically input into Portfolio #2's XYZ stock slot.
