Weird Glitch?

[Ssharif0402 6]

I started a new playthrough on easy difficulty after beating the game on medium almost a year ago. When i was playing, the trophy "resurrection" popped again even though i had it already. Before anyone asks, i'm on the same psn account as the one i used when i first played it. When i went to sync my trophies, the date didn't change, so it was probably harmless but i'm still pretty concerned. I should also add that i'm playing on a different system than the one i used previously, so maybe the trophy data hasn't been installed properly.
