That seems like a product defect. Did you try snapshotting a similar object like httpd.conf and try exporting those results? If that runs into the same issue, then it's a defect across the board. Otherwise, it could be an issue only with the httpd.conf file and the way the results are being stored in the db.
Do the snapshot results show up in the report? May be you can try exporting the results from the report and see if the values show up.
I had a problem in 7.4.6 where I was getting extra fields in my snapshot data - so instead of value1-3 i would get value1-27 where it was 123,123,123,123...
