How come no one's ever reported these bugs as I found they have persisted since v3.1.6275 right after the implementation?
1. If you try to open sub-folders with "show count" option enabled, you get this error. If you can't reproduce it, try keep changing selected category between folders and others. With show count disabled, it works fine.

2. If you import multiple files from the same top-level folder, it for some reason lists the same folder multiple times. If any of its sub-folders contain library files, then each folder shows the same tree of sub-folders. Of course it shows the same items if you click on any of the same folders. The following screenshot shows C:\test 5 times, which means 5 items were imported from that folder including other items from its sub-folder a, b, and c. It only happens to top-level folders.
