Query: Upstairs/Downstairs subtitles don't work

I was so excited to get this anniversary edition at a good price. The first set arrived and the subtitles did NOT work. I returned and received another set very quickly. Amazon's exchange/return process is very efficient. Unfortunately, the second set's subtitles did NOT work. I've sent this set back as a defective product and expect a 100% refund. Are any of you having the same issue with the subtitles? I order from Amazon all of the time and this is the first time that I have been disappointed.
