Many of my feeds are not visible in the left-hand tree viewer. The tree shows three categories - Cars, News, Tech and each category expands to show a number of feeds (18 in total).
However, if I select File -> Manage Feeds, there are 26 feeds shown in the list on the left. Mostly these seem to be items setup with Feedreader and that I don't want anyway. However, the big problem is Engadget, which I would like to see.
After the categories in the tree list, there is an unread articles item. I can select this and then see Engadget items. It appears that the feed exists and is being updated correctly, but is not visible in the tree view.
