Missing plate in manor?

So I just got platinum and I went back to the manor to check out all the collectables in all the rooms and I noticed that in one of the cabinets on the left side a plate is missing on the bottom row 3rd in. Does anybody know what that plate is? The only thing I have left in my log book is the encyclopedia mission. I finished it but I dont have anywhere to turn it in. Is it maybe that? or is there something else that I am not aware of.
