They're web releases and not blu ray releases, which has many Fixes to the web version. It's the same case with the anime 91 days(best release is UDF), These are the results. For example, attack on titan s1 best release is done by SCY and when I search for it on your site These are the results, not only the search is kinda broken (I clicked on This which is season 1), It doesn't display the best release (which is done by SCY). Basically, we choose which release group we should go with by going on seadex and searching for it.

For torrents, whenever a show has finished airing and has a BD release, there are best releases which are chosen by people who understand things about encoding and artifacts and they then update it on the Seadex. I personally still feel that nyaa is easier to use (and better if you follow the wiki).
