When you're in a title record in staff client, and you click on the Modification Log tab, the viewlog.pl script is displaying inappropriate entries. For example, on biblionumber 6364, it's showing entries for that plus biblionumber 16364. Same for the pair 16314/6314. It seems like instead of doing an exact match on the biblionumber, the log viewer page is doing a wildcard -- anything _ending_ in 6314 instead of exactly equal to it, so it's pulling up invalid entries from the log table. I do not see this happening on patron log entries, but I have a very limited patron set in my test database.
