I am sorting numbers in a column. All are formatted number. When paint the
column to sort, there are some numbers that will sort and others don't so
anything.

They look like below:

79668
79672
79762
73025
73026
73027
73033
73042
73050
73057
75028
75029
75031
75053
75057
79637
79638
79639

Why won't they all sort?
