There could be a glitch in the system that is preventing the match from showing up. Earlier this week I noticed that the chromosome browser at FTDNA quit working for my dad's kit. The list of his matches shows up in the selection box on the left, and it says the number of matching segments in the selected matches list at the top when I select some of them, but the actual chromosome image, tables and downloaded csv files are all blank as if he doesn't have any segments in common with anybody that I select. I'm not having any problems using the chromosome browser for any of the other kits that I administer. I have reported the problem to them and they sent back a message acknowledging that they received the report, but it still hasn't been fixed as of this morning.
