Separate Night Trap and Sewer Shark Sega CD versions

Can you give me a bit more info about this and links to the different versions so I can look into this more?

Night Trap - Sega CD

If you look at the images on the link above, you'll see there is box art for two distinct versions. One is the original first release in a red box with no rating. Later on, after the creation of the ESRB (largely created due to this game specifically), a new version was released with the updated Sega CD blue spine and an M rating.

Currently, there are separate listings for the 2021 reissues done by Limited Run, but the original two versions from the 1990s are listed as just one release.

Sewer Shark - Sega CD

At this link, you'll see images for two different versions. One is the original retail release that came in a black box, with a black disc. The second version came only as a pack-in with the Model 2 Sega CD system. This version does not have a retail box. It only includes a blue disc with "Not For Resale" printed on it, housed in a generic CD jewel case with no inserts, and a smaller manual with a blue spine:

Sewer Shark is perfect, however I feel the original red box Night Trap should remain as Night Trap (as it's the oldest), and the Blue Band should be labeled as [Reissue], I just posted a bug about this a short time ago.
