[Gallery] Content not installed - You own everything in this gallery item

Pretty much every time since the patch that screwed with the gallery, when I want to place a lot from the gallery I get the notification:

Content not installed
Purchased or other content used in this Gallery item is not installed. If you place it now, you will not see the uninstalled content.

Huh? Uninstalled content? Did someone use AI to write this? And why does it trigger even though the window behind that says "You own everything used in this gallery item" ?

Now Im getting THREE such popup notifications before placing a lot. THREE!

Content not installed
Furnished or unfurnished?
Replacing an empty lot

Seriously?! Im glad maxis doesnt build cars. The airbag would ask "are you sure?" before activating. This is how this crap feels like.
