I'm not sure why that is. I took a glance at your GEDCOM and it looks like you've gone through all the Suggested Matches. If you want to click "Approve" again I'll watch for it when I review the GEDCOMs in a bit. One thing you'll want to do before you approve it is go through and skip any individuals who don't have a birth or death date. They are easy to find if you sort by "Birth". If you have any questions, let me know. Thanks!
