    Another thing I don't understand is that this new match has a genetic distance of 6 at 67 markers (and 10 at 111 markers) but doesn't show up at all at 37 markers.
    each level of matching only allows for a set number of mismatches (note, if one person has a marker value of say 17 and the other is 19, this counts as 2 mismatches or 2 GD)

    12 marker - exact matches only, 0GD, exception GD of 1 matches shown if both are members of same FTDNA project
    25 marker - up to 2 mismatches, 0 - 2 GD (includes 12 marker level)
    37 marker - up to 4 mismatches , 0 - 4 GD (includes 12 and 25 marker levels)
    67 marker - up to 7 mismatches, 0 - 7 GD (includes 12, 25 and 37 marker levels)
    111 marker - up to 10 mismatches 0 - 10 GD (includes 12, 25, 37, and 67 marker levels)

    You would have to look at your markers and this matches to see where the mismatches are, at least 5 of them must be on the 37 maker level or lower for them not to show up on those levels of matching

    ie) Hypothetically
    1 mismatch on 12 marker level, will not show as match as only exact matching shown (exception will be shown if both in same project)
    additional 2 mismatches on the 25 marker level , will not show as a match due to fact you are a GD of 3 on this level and only up to a GD of 2 shown at this level
    additional 2 mismatches on the 37 marker level, will not show as a match due to fact you are a GD of 5 on this level and only up to a GD of 4 shown at this level
    additional 1 mismatch on the 67 marker level, match shown due to fact you are a GD of 6 which is under the 7GD max for this level
    additional 4 mismatches on the 111 marker level, match shown due to fact you just make the maximum allow GD of 10 allowed for this level.
