It's not incorrect. The Lord is My Shepherd is missing a scene shown in the UK (the scene is on youtube.) It is a longer scene of Pa/Ma leaving for the doctor in the carriage. There is a scene at the end of Country Girls that was on the Imavision set that isn't on the blu-ray. This scene features a boy reading a lot of his essay after Laura finishes her reading. These are PAL episodes from the UK cuts. Also, the editor is different on some of the UK versions compared to the US according to the end credits (still a US editor.) It has happened with other shows...ROOTS being one of them. Downton Abbey has scenes in the US that aren't in the original UK (also US) blu rays.
