Question Match at Gedmatch but not at FTDNA

I'm puzzled. I have a match on Gedmatch at 20.5cM total & largest segment 13.6cM, according to the one-to-many tool. We both tested at FTDNA but donít show in each other's matches at FTDNA - which we should, given the matching-threshold options of either one segment >9cM or 20cM in total with a minimum 7.69cM single segment. (FF thresholds discussion http://forums.familytreedna.com/show...t=42523&page=2 ... especially KATM and Frank Kelch's posts towards the end of p2)

A one-to-one comparison of our two kits at Gedmatch shows only the 13.6cM segment >7cm; but at <7cM there are another 10 matching segments.

My lowest matches at FTDNA are (total/longest cMs):
18/9
17/13
16/13
13/13

I thought the problem might be settings, but now I'm not so sure. My match changed his Matching Preferences from "distant, close & immediate" to "all levels". He did this about 12-14 hours ago, but I'm still not seeing him.

Can anyone think of any other reason why we wouldnít appear on each otherís FTDNA matches list?

FWIW, part of the 13.6cM segment is in the pile-up area on Chr 17. I didn't think that affects another FTDNA tester appearing as a match, but I could be wrong
