About why discs come out with cut or edited or wrong transfer versions there may be many reasons that could include time is money, carelessnes, lazyness, human error, and just plain Sentient Evil!
But seriously, probably was the existing master of an existing print
(and/or was the way the program was originally assembled/designed.)
I'll tell a unrelated/related

story (courtesy of S.H.) about strange stuff that can happen behind the scenes
The Beatles in England originally released the Magical Mistery Tour movie songs in 2 EPs. That same year they had also released 3 non album 45RPM singles. Those EMI vinyl thinguies were all mastered from the original First Generation tapes. Now, they did copies (2nd generation) of those separate EP and singles tapes and sent them to the US where Capitol yet again made copies (3rd generation) to assemble a master reel for cutting the US-only Magical Mystery Tour LP. Now, a few years later EMI UK wanted to release all those separate EP and singles songs in a single LP too. Did they just assemble the 1rst generation tapes they had sitting on the shelves right there in front of them? No!, they asked Capitol for a COPY (4th generation) of their tape to be shipped back to England! Sooo instead of having an LP made of the real tapes, they had a LP made of a dub of a dub of a dub of the tapes they had in the next shelf.
You wanna a sadder story?

When a few years later an Audiophile company in the US wanted to make a super duper LP version of the album they requested the Original Master tapes, and guess what they got sent all the way from England, and used? That dub of a dub of a dub of the original tapes cus that was the LP "master". It woulda been better they had gone next door to Capitol and asked for the earlier tape it was made from!!
Hope this explains the unexplainable.
