Perplexing! Very few T's in that title. Do make sure that it's sorted by title in Pocketpedia as well. Footer will mention what the collection is sorted by and try changing the sort with the sort button and then back to title. Also please double check your sort title column in DVDpedia, that is really the only reason I can come up with that "Master and Commander" would appear under T. If nothing fixes it, do send me your data file as I unable to repeat it here with adding all 6 Doghouse copies of "Master and Commander" to different collections.
