Row sorting is off when empty cells present.

This may take an image to explain (attached) but here is a try with words too.
The output is simple tv shows in a week date range.
Columns = day
Rows = Time

So 7 Columns in this case for 1 week.
If Monday does NOT have an 1:30 show on BUT Tuesday does instead of putting a empty row for Tuesday to have a spot it ignores all 1:30 output UNTIL the end.
After 12 am on Monday it starts over till finally on Tuesday there is a row for the 1:30.
This goes on down the line and is the only thing I can think is going on. I know for 99% certain it is not the data.

bty thanks for this great module.
