[Ifeffit] The missing feff paths

Hi, I have a problem when I used Demeter 9.18 or 9.20. The Artemis window only show parts of the calculated feff paths such as the followed figure (only 0, 4, 5, 6, 7, 10 paths of the first 10 paths were shown, and where is the other paths?). Did anyone meet this problem and how did you treat it? Many thanks! best regards, Qiantao Shi Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences
