Most of these are friends' sites that I entered manually just to get it going, so I don't expect them to have an R-link, but, as it happens, the two culprits that entered an R-Link URL to a page that is up but does not have an R-Link on it are the notorius Dew-Code (#1) and the Arbor View B&B (currently the newest).

However, I tried entering a valid URL to a page that does not have a link to my site in another site and saw that after that it also came up w/ the Delete checkbox checked by default.

The reason I thought it might be a bug was because it was my first and last links only, which turned out to be just a coincidence.

I'll check out the widget..
