[Ifeffit] Bug in Artemis

Greetings! I encounter an issue for which I find no explanation so far. When I try to export data and fit in k weight 2, the data gets exported in k weight 3 all the time. I can see that Artemis k weight is 2 but Artemis output k weight is 3. Everything was working properly until today. Does anyone knows how to change this Artemis output k weight? Thank you very much in advance! Natasa
