Same issue on latest Ubuntu Focal with GNOME Software 3.35.91. I have tried multiple different deb packages (Skype, Visual Studio Code, BlueJeans etc.) and there was exactly the same problem with all of them.

Manually installed deb package (that does not contain any AppData), for example Steam from Valve (https://store.steampowered.com/about/), cannot be uninstalled using Ubuntu Software. The manually installed package appears under Add-ons section on the Installed tab, but it is gone after Ubuntu Software is restarted. When right clicking the Steam icon in GNOME Shell Overview mode and selecting "Show Details", details page with Ubuntu repository version of steam-launcher is displayed instead. The only way to remove the deb package using GUI is downloading it again, clicking "Install", then clicking "Remove" before closing the app details page.
