After a review of the importing process, I found the problem and have taken steps to correct it. This means adjusting all the analyses with updated charts and re-writing parts of the analyses. The corrections are mostly minor, but there was a few items which just couldn't be let go. So it was my decision to start again to make sure that the analyses were thorough and correct.
Without dwelling into the details it had to do with the difference of working with binary networks and weighted networks. If that makes sense to you, then kudos. If it makes no sense, it won't matter in the long run.
Thank you for your patience.
