Difficult to believe. The proposal was tested with your sample in post#1 before posted with the given result, and a repeated test now yields the same.
So - the difference must lie in
- the awk version - which is yours?
- the input file / file structure
- correctness of copy and paste the program
Please post the conditions that you ran the program in.

One suspicion: an empty line in (at the end of?) the input file. Result with an empty line:
Code:
col1,Sum of col4,Sum of col5
223,10,13
227,7,2
228,12,34
,0,0

Can someone explain what might be causing this?
That's the result of your data having empty line(s).
