In the System Settings > General > Login Items & Extensions - Extensions pane, when I select the By App tab, I can see multiple instances of extensions for different applications and sub-types. e.g. Books (from Apple) is listed twice with the Sharing subtype.
For the specific extension I'm checking, I can see multiple instances listed for the File Provider sub-type.
The number of instances does not seem to correspond to anything.
There are 5 instances listed and it seems like these are not exact duplicates because when I disable one using the (i) dialog, the others are still enabled.
This number (5) corresponds to nothing obvious:
- at one time, there is only 1 instance of the File Provider (a Finder Extension) installed.
- if I use the pluginkit command line tool to list the extensions, it only reports 3 known versions of this extension.
As a developer I'm puzzled by this list with duplicates. As an end user, I'm totally puzzled by this list with duplicates.

[Q] What is this list in the Login Items & Extensions pane supposed to represent? Is it known to be buggy when it comes to its contents?
