duplicated "Another World" app in the repo

Installed Flatpak apps can be duplicated in Installed and Repository lists.

Following conditions seems have to be met for the problem to show up:
- the app must be exported to some local repo
- the app must be installed (from the local repo or directly from build-dir, doesn't matter)
- the app must contain AppData xml
- the AppStream must be exported to the repo from app's build-dir, and then updated to flatpak itself:
$ flatpak build-export --update-appstream repo build-dir
$ flatpak update --appstream

Can you provide the commands you follow to create the repository? It will help to reproduce locally and work into the fix.
Comment 3 Andrey 2018-12-13 14:12:52 UTC 
Aleix, it's just as simple as this:
$ flatpak-builder --force-clean --user --repo=repo  build-dir org.flatpak.Hello.json

You can use random manifest here. Just make sure you have installed the same app
Comment 4 Andrey 2018-12-13 14:14:14 UTC 
To add the repo:
$ flatpak remote-add --no-gpg-verify --user test repo
Comment 5 Andrey 2018-12-13 14:16:41 UTC 
Important note:
the App ID should not be present in any other repositories than local repo!
Comment 6 Andrey 2018-12-27 20:30:37 UTC 
Nate, it would be fine if you try to reproduce this.
I can't check non-flatpak version
Comment 7 Peter Eszlari 2020-04-23 13:00:21 UTC 
I found to causes for duplicated entries:

1. appdata.xml is split from the main package

example: kdenlive in Ubuntu
/usr/share/applications/org.kde.kdenlive.desktop in package "kdenlive"
/usr/share/metainfo/org.kde.kdenlive.appdata.xml in package "kdenlive-data"

2. distribution package doesn't ship a appdata.xml file

example: blender, dolphin-emu
Comment 8 Peter Eszlari 2020-04-23 13:04:03 UTC 
Of course, the third should be well known:

3. The <id> tag in the appdata.xml files don't match and <provides> is not used.
Comment 9 Nate Graham 2020-04-23 14:09:31 UTC 
Yes.

These are problems caused by the packaging and unfortunately not something Discover can fix. We can make the duplicated display look less duplicatey though. Marking as a duplicate of that
