Question about using the Grid

When I use the Grid to screen for

Age > 90 days,

Sharpe > 2,

Trades = Stock,

I get a list of 10 systems. mvp-3 is not one of them. But reading mvp-3’s description, it seems to meet the criteria. So why is mvp-3 not showing up on the Grid?

Not enough trades yet. I think 7 are required.
