Hmmm ... the Bride and groom have a "principal" interest in a wedding and should be included no matter what. Have you run a report (make sure to select the event option) to see if they are associated with a principal role?
What version of UFT are you using? Before I'd ever go through and edit EACH event, I try two things. These ALWAYS my first two suggestions ... and people are probably getting tired of hearing this. :)
1) I would first try the FIXME.Bat This will restore UFTree database configurations without hurting any of the data. 2) You might also try the Utilities/Check/Repair options and see if that fixes items.Inconsistent links are repaired in this process, if that's what's missing.
