Im playing for the first time, and was gathering all collectables in galata, as i was gathering data fragments, i noticed an inconsistency. When i gathered my 5th fragment, the game stated 5/11 onscreen and i was informed that i had unlocked one of desmonds memory but when going into my DNA and lookign at additional memories, it only showed 4/11 for galata. I continued picking more up, and each time the game told me id picked up a certain amount, the dna page showed 1 less. Ive just picked up my 11th and final memory for galata, and it stated 11 on screen, but no surprise the dna page shows 10/11 for galata. Ive quit the game and gone back in, but it still only shows 10//11 for galata. Since its early on its not a big deal restarting the game, but id prefer not too. Is there something im missing? is this a known bug, can it be resolved, or am i screwed.

playing steam PC version BTW
