All of them should be deleted.
Volume 1 and 2 are compilations and the other two are DVD specials.
Clone Wars is specifically used as an example in the Bible for what's not allowed so it's especially weird that these were added.
Not Allowed: Director's/Extended Cuts and DVD extras such as: bloopers, making-ofs, deleted scenes, cast interviews (unless streamed or aired). Also not permitted are compilations of seasons merging every episode into one long video featuring little to no changes (i.e. 2003’s Star Wars: Clone Wars).
