Currently the database shows separate BD releases for the series, i.e., separate cover art for each season. But, the complete series does not contain five seasons worth of HD Keep Cases. There is a single, larger, HD Keep Case that holds all 10 discs. Shouldn't this listing not be in the database as a box set, but as a single release with the 10 discs? Frankly I have no idea how to combine the 10 separate cast/crews lists into one if the listing were to be changed in order to be more accurate as to what it is.

I think I figured out how to get the cast/crew from all 5 seasons into this release. The cast dividers worked out fine, in that I was able to add group dividers for each season. But, for the crew, the group divider was not cooperative. I was not able to group each season on its own. Whenever I tried to add a group divider, it kept being placed in one of the crew types, i.e., like Music. I ended up adding episode dividers. But, I ultimately think that will not result in a crew member being listed correctly, i.e., assigned to a particular season and episode. I'm thinking that maybe each episode divider should prepend  "Season n - " to each episode number.

Consensus? Off my rocker?

You should use episode dividers both for the seasons and for the individual episodes.
That goes for both cast and crew.

I did the copying and pasting as @huskersports suggested. I discovered that while doing right-clicking in the areas to see what I would get.

This is what I ended up with before @huskersports amd @GSyren made their suggestions:

You don't need those "Season 1" and "Season 2" dividers at all. So, put 1-1. Live and Learn, then 1-2, 1-3, 1-4. etc.

For the 2nd season example in your picture, put 2-1. Worlds Apart, then 2-2, 2-3, 2-4, etc.
