I came across some interesting behaviour. It doesn't seem to be problematic, but I'm reporting it just in case (and because I'm wondering what's going on):

I use a single reading list with "replace device with list, add new items only."

I have several virtual libraries. Half of the books on my list are viewable in the "Default" VL and the other half are in the "Fanfiction" VL. (I used to have a separate list for each VL, but it caused replacing issues described earlier in this thread.)

When I finish reading a book, I remove it from the list, add a new book to replace its spot, and then sync the list to my eReader. However, if I'm currently viewing of my VLs, it also re-uploads every single book from the other VL as well as the new book. (Interestingly, the re-upload doesn't affect the reading place on my eReader, though that may be because of Kobo Utilities.)

The solution is a pretty simple one, just switch to "all books" before syncing. I'm mostly just curious as to why exactly it happens.
