That's weird?Mine are equal and I get the achievements at (almost) the same time.

Hold on back up idk how to read. You have one for opening and one for finding. It's obvious that if you FIND but don't open,the count will be different?

/I bet I didn't get it better

I see one for finding them and one for opening them, but only one for each. You definitely see two achievements for opening them?

As previously mentioned, one is for finding them and one is for opening them. :)
