I added new elements (448, 451, 454) to group "??????? ??????" of list 19 (totally has 7 groups of elements). A copy of this list with ID 22 has not group "??????? ??????" and consists of 2 groups form the original: "??????", "????????????? ??????". I have no idea why, but new elements were also added to a list 22 within group "??????". I should say that I had similar problems (random adding new elements in copies of mail list) before. Rob, can you fix this bug? thank you!
