Upgrading nfdump from 1.6.22 to 1.7.5. nfdump returning different data

[SandorGardil]

Hi I'm updating a nfdump to 1.7.5 in a project and don't have too much experience with nfdump so sorry if this is a bad question. I had previously asked about my nfcapd not working and was able to get it work, or at least recieving data, with your help. Now it seems im running into issues where we use nfdump to update our rrd file. While trouble shooting I ran this command on one of my flowdata files
nfdump -r {path-to-flowdata} -s dstport -n 1 -N -o csv
and the data that was returned is different between my 1.6.22 machine and my 1.7.5 machine, where the 1.7.5 machine is missing the summary data. I read the man pages for nfdump and the flags seem to be the same so I am a bit confused. Any thoughts on what the issue i'm having may be? Any help I can get is very appreciated, thank you.

Data from 1.6.22 (the type of data I would like to recieve):

Withe nfdump-1.7.5 the old legacy csv format has been updated into a more flexible and configurable csv output. Strincly speaking, the summary line would pollute the output, as the first line defines, how the following listing is presented. The summary block would not fit anymore. Therefore it has been removed.
If you still need a summary block, rerun nfdump, but use -o null instead of -o csv.

Awesome, rerunning the command with -o null did the trick with some formatting of the data. When you mention that the summary line would pollute the output, was it not intended to be included in the csv data in older editions? Thanks for the help!
