Apparent duplicate testimonials if all sort order fields are zero

[losttheplot]

If you have more than 20 testimonial records in your db and do not set the sort order field on any of them, the records will be listed randomly in the admin display. When you then select to view the second page of records, you appear to have duplicate records because there is no reference as to which was the last record on the previously viewed page. May I suggest that you use the ID field as a primary or secondary sort index when viewing records in the admin display.
