I have this collection and mine doesn't do this. One thing I did notice though is that if you open a game not installed and it goes to the game page. If you do not close that game page opening another game doesn't close the previous one. For example if I open up a C&C title and Origin goes to that game page, if I just close or minimize Origin and then open up a Mass Effect game, Origin just opens back up the C&C title. Could this be potentially what you were running into? If not could you do me a fvor and reimport and turn OFF LaunchBox Games DB search. Other thing I could see being a potential issue is a match gets a bit greedy and changes the title causing some confusion (though I don't see how it would match it to "Ultimate Collection Additional Content")
