Well, it is another way of doing it for multiple chips, so that they help to simplify and clarify the scheme when using them, wich is the important thing, avoiding that they are stuck.
The package 4538.package.d is only informative to see the physical distribution of pins, that's why i haven't put any internal connections in it (never to be used, for that is the LS) and I also put another extension so that it doesn't interafect with the LS package.
So everything works perfectly as you can see in the attached circuit test and example of use.
So it's not a error, it is made on purpose. Individualizing multiple circuits is easier to use, more instructive, easier to follow, etc. Otherwise there is a swarm of cables that make it difficult to design and understand the idea. An scheme should be like a work of art that invites you to see and appreciate it. I use this concept in all my works as you may have seen.
