GNOME Software showing duplicate installed apps

[Justin]

In the software store on Ubuntu Gnome 17.04, fully updated, some apps show up as installed twice without be doing anything command line installs, updates, etc. This currently effects the Software & Updates app and Chromium app (installed from the most popular software store options, I'm also confused why 3 show there). I installed re-downloaded images on a second computer to verify this
issue further. Print screen showing the duplicates attached. Several other apps showed duplicated on installation (including ImageMagick), but went away after rebooting.

Reinstalling on another system reproduces two of the other duplicate apps that I lost earlier and they won't go away: font manager and GNOME Control Center. They won't go away on the new install.

And photos.

Status changed to 'Confirmed' because the bug affects multiple users.

Duplicate ImageMagick occurs in 16.04.2 as well.

I have a feeling this might be related to multiple APT lines in /etc/apt/sources.list - these should be de-duplicated in GNOME Software?

It affects me as well (Ubuntu 17.04). Screenshot is attached.

I have a fresh new install of 17.04. Quite a number of applications are listed twice. (On my system at least, the duplicate listings have a "Source:www.ubuntu.com" in tiny text below the description.)

Fix verified in current release of 18.04.
