Yes I noticed that too. Over the last few days I downloaded The Simpsons. I started with version 7.0.2.5 and later had to create a Python script to shift all seasons down by one at once. So far, I’ve only noticed it with The Simpsons, but it will probably happen with other series that have “exclusive content” as well.
It seems to be caused by the patch from 7.0.2.5 to 7.0.2.6. Before that, after scanning, all seasons “Exclusive Content” was recognized as Season 1, which was fixed in 7.0.2.6. However, when downloading, for example, Season 26, the season numbering is still one season higher than before, probably because internally it still recognizes “Exclusive Content” as Season 1 in SF 7.0.2.6
