Hi AriaUpdated I hope this is ok to be posted here. There are at least 2 uservoices stating that it is becoming a big issue for users that 1903 / 1909 / 2004 / 2004 (and soon 20H1) so basically all that allow a enablement package show the same version in WSUS
this is not helpful for reporting it is not like this cannot be fixed.

Add build number to WSUS – Windows Server (uservoice.com)
Why I know this and this is not a "by design" issue: AJtek WAM script from AdamJ does fix this by altering the database string based on the OS build.
I really hope, that you can convince the team to update WSUS database.
