Unfortunately that's pretty normal. I've never received an LV item with the plastic attached. I've seen others post here who have, but I'm guessing it's not their standard practice at least here in the UK. I've received pieces with hardware like that. It doesn't bother me too much because it will happen almost instantly with use, but I agree it should be perfect when purchased new. You could always return and specifically request one with the plastic still attached. I don't see why they would refuse if you ask.
