Ok. The Watching tab thing was something someone requested, for reasons I now dismiss thanks to your note. It is reverted to previous operation.
Here's how the import works now.
1. We grab the first 200 items.
2. Iterate.
3. If it isn't in our database yet, it is added.
4. Otherwise ignore.
And so after carefully reading your post, yes, it is quite possible that you have something on your watch list that ended and is polluting the list.
While I'm at it --- as this bug made it evident from other posts of the extraordinary value of the Import feature --- I can improve the import feature to check to see if there is more than 1 page, and then just grab all of them.
Give me a couple of days. Thanks.
