MIN for different columns of same values produce different results

I do not understand why results are not equal for two different columns with same values. Maybe someone can enlighten me of something I'm not aware of.

Example:
1st column is made up of cells with =IF(AND($E9="x",G9>=1),G9," ")
2nd column is made up of cells with =IF($A9=TRUE,$G9,0)

The resulting values for both columns are the same for G9.
MIN(Range) of the 1st produces a number.
MIN(Range) of the 2nd produces " ". I copied and "pasted special" values in to remove the formulas and still get " "

Any suggestions please?

I have the zero values turned off on the sheet so guess what I was referring to as " " are zeros. I can do a partial of the range that has only numbers and get the proper result but when I include the whole range with the 0 cells it returns 0. No error values are displayed. The 1st column is formatted the same and has zeros in it and returns a value with the complete range.

Figured it out. I changed the false result in the formulas in the 2nd column to " " rather than 0 and that corrected it.

=IF($A9=TRUE,$G9,0) to =IF($A9=TRUE,$G9," ")
