When trying to import my schedule recently I have run into a continual problem. I am currently on reserve which I understand doesn't show up as duty periods when importing. What I have found is that if I am later assigned a trip which I then attempt to import using the download schedule function, a problem arises in a couple of instances. If either if I have manually created a duty period (like a reserve duty period) or if a company specific code was used(in this case a simulator seat support duty, CRW2), the imported trip combines with the other period. This has happened to me twice, once in both of the cases I listed above. It doesn't matter what days the assigned flight is vs the other duty period. In the attached screenshots, the CRW2 pairing was just a training event. The trip H3167 was assigned off of reserve on 30 May. When I imported the schedule, this was the result, with the information for H3167 displaying on the wrong days under the CRW2 heading. I deleted the CRW2 duty period, however when I was assigned a trip in June, and selected download schedule, it again created the erroneous combined schedule for the previous month. Manually downloading a single trip the old way works fine.
