The problem seems to be that the code doesn't understand that if column 5 only have 47 elements, then column 8 might have 49. Because when a column is having more elements than the column with the preliminary lowest number of elements, the extra elements is skipped.
Example: Column 5 is having 47 columns. Then none of the remaining columns will have more than 47 elements (even if they actually have). If column 12 then has 45 columns, the remaining columns will never have more elements than 45, and so on..
