According to my geocaching.com statistics I have 4 blanks in my D/T matrix, according to project-gc.com there are 5 blanks, it shows an additional blank for D5/T3,5. I have checked the My-finds-query and there is a cache with D5/T3,5 (GC4DKBN, found on 2014-05-13). How come this one isn't displayed on project-gc? It also doesn't appear in the "way to the 81 matrix"... But the number of founds is right...
