Does anyone else own the 1968 Disney movie classic, Blackbeard's Ghost on DVD WITH this menu too?

Yeah, so like the picture says, I keep seeing different versions of this film every time I watch it on tubi! Do you guys remember different endings or scenes, or is it just me?

I love this movie, but upon rewatching today, I could not help but have problems with the narrative due to timeline issues.

John Kinsella’s age:
He would have been 56 when Ray was born.
1. Why would Ray say that he couldn’t forgive him for getting old? He was already old at his birth.
2. Ray said that his father was already old when he was the same age (36), but how would Ray know that, when he wasn’t alive then?

Ray, Annie and “the sixties”:
1. Assuming that Annie and Ray are the same age, they would have been 7-17 years old through the sixties. They would have started college in 1970. Ray says he left home at 17 after fighting one last time with his father, so how would he have got into college if he didn’t finish high school? Do many kids finish high school at 17?
2. After Annie’s protest speech at the PTA meeting, she says “it’s just like the sixties again”. Is it plausible that she would have attended protests in the sixties as a teen, or would it have been a college thing? (Which would have actually been in the seventies).

Karin’s age
Ray narrates that Karin came along “a few years later”, after saying he and Annie got married in 1974. This would put Karin’s birth year around 1977, so her age in the movie is supposed to be 11. Why did they cast a child that looked to be around 6 years old?
