Well spotted, Peggy. Bubner-10 had the DBE 587 suggestion with info field 155409138. The link on the profile was to
https://www.findagrave.com/memorial/155409138/albert_keith-bubner
This contained an error: the character between albert and keith was an underscore _ where it should be a hyphen - like what is between keith and bubner.
I have edited the profile and replaced the underscore by a hyphen. That should fix the suggestion.
However, I'm not sure how this relates to the problems that Dave reported.
