I hope my title pleases the descriptive title Gods. I ran out of characters but the last word should be "formulas"

For some reason. When I click the little arrow next to a column title in this table I created doesn't properly sort. The values in the cells are numbers that are the result of a formula. Columns that have numbers entered directly appear to sort normally. I'm obviously missing something here. I've sorted values based on formulas in the past with no trouble.

Thanks
