Shrek compilation videos

Hello all. There's a few Shrek compilation videos/series on IMDB. As far as I'm aware, all these projects are just the previously released listed titles put together without any new linking material. These are:

Shrek's Thrilling Tales: https://www.imdb.com/title/tt2486724/ which consists of these three shorts: https://www.imdb.com/title/tt2087984/ , https://www.imdb.com/title/tt0360985/ and https://www.imdb.com/title/tt2090578/ 

Dreamworks Spooky Stories: https://www.imdb.com/title/tt3608838/ which consists of these shorts: https://www.imdb.com/title/tt0360985/ , https://www.imdb.com/title/tt1482967/ , https://www.imdb.com/title/tt1725156/ , https://www.imdb.com/title/tt2051999/ , https://www.imdb.com/title/tt2087984/ and https://www.imdb.com/title/tt2090578/ .

And then there's DreamWorks Shrek's Swamp Stories: https://www.imdb.com/title/tt6950338/ , which again consists entirely of the previously released and listed https://www.imdb.com/title/tt1725156/ , https://www.imdb.com/title/tt2268617/ and https://www.imdb.com/title/tt0438844/ 

From what I understand, these are not eligible to be separate IMDB titles. I'm posting it here so people can look into it. Many thanks!
