Baby shower registry gifts. 😕

Had my shower yesterday. It showed on my target registry that gifts were fulfilled. I ended up with nothing purchased off my registry, instead I received a bunch of stuff I dont need or I already had for baby. Has this every happened to anyone else? Im not sure where to take it back. I'd like to try to exchange them for stuff I wanted. If not, ill save them for a friend or family who might need them later.
