Why does it says I don't qualify for the home office deduction because my net profit is zero or less when it shows that I did make a profit? Everything else is correct.

When I look at my business' net profit comparison, it shows that I made a profit, however, when I fill out the info for home office it says that I don't qualify because my "net profit is zero or less." I qualify under every other circumstance and have qualified every year. So why?
