From what I've seen, almost all self-published books on Kobo get a Book ID which looks like 1230008927877 which is not a valid ISBN and likely the reason the field is now labelled as Book ID.

A while back I had an issue with one library book where I got the wrong book from Kobo since the self-published book had the same ISBN as the library book. A while later I noticed their self-published books now had ISBNs starting with 123 which was likely to keep that issue from reoccurring.
