I'm using Ubuntu Touch 14.10 on the BQ Aquaris 4.5
Today I went to the System Settings app -> About this phone -> Storage
and I'm able to see every app I have already unistalled. Also the ones I have upgraded are displayed twice (I suppose they would be displayed three times after the next app upgrade).
I tried rebooting the device and searching google but so far no luck with both.
Here's an example screenshot of what I'm talking about:
In the picture you can see the Music and My Photos apps two times and I've already removed Instagram Photos but it still shows it.
Everything is displayed normal on the Apps screen - upgraded apps are shown only once and uninstalled are not showing at all.
//EDIT:
The same thing keeps happening after the 15.04 update.
