They probably only printed 35mm negs and never felt a need to remove it ---- unfortunately.

If you intend to mix formats you will need another sized carrier which gives you the opportunity to clean the mating services that sandwich the carrier and put in place proper seals to prevent light spillage. Even if you intend to only print 35mm negs you will be better served with fresh seals.
