Behavior/Resource Pack/Add-On Version not visible

This is rather an inconvenience than a bug. When I develop my resource pack and
import a new version of it the old version is still visible
in the global resources menu (see screenshot). The problem is, that you can no longer
tell apart which is the new and which is the old version.

The problem becomes even worse, if you add updated versions of the add-on to a world.
Then you get the whole add-on history the world ever had, without a way of telling
the versions apart.

The only place where the version is visible is the "Storage" menu.

Expected behaviour: The version of the add-on or pack is printed below the
name of the resource pack in the Global Resources and the Resource
lists when configuring a world.

On top of that, I found no description about the supposed update process for
a behaviour/resource pack/add-on. The wiki only documents the basic file format
of manifest.json.

I am a software developer, so handling JSON files is not foreign to me.
But the semantics of the version numbers should be explained, especially
in a context of "updating" an add-on.

Here is my manifest.json for my resource pack add-on for reference.
I changed only the "version" fields without touching the uuids, if that is wrong,
please give me a pointer:
