well the 4 shelves I'm assuming are in the lounge where the floor accolades are supposed to be, but I can't find any of them. I've looked up where the poker table is, behind in the kitchen and where the couches are below the federation banner but to no avail. Does the bridge layout make a difference (small, medium, large)?
In the crew lounge for feds and mess hall for KDF there are 4 wall/shelf mounts, 2 on each side of the floor trophy mount. It faces the bar.
In addition, the captain's ready room for both fed and kdf have 2 wall/shelf mounts
Interior layout makes no difference, the rooms that these are in are exactly the same.
