I was just playing around with the Sim account feature in NT7, and noticed a simple bug that would be easy to fix.
1. Take any account starting value, in terms of cash.
2. Buy X amount of shares/contracts/whatever with it. You will see that the maximum limit of Y is reached.
3. Now repeat step 2, but go short instead. You will noticed that you can open twice the short position (i.e 2 times Y) in terms of size as compared to a long position.
This should be easy to fix, I think your calculations are just off for the short side somehow.
