My job program got changed to CB when it should be MG?

So I ship out Monday next week and I’m coming to MEPS tomorrow for processing and stuff. I sign a paper that says CB and you need to have like 95 on your ASVAB? I didn’t get 95. Anyways I sign the paper and I notice this and tell my recruiter that it says CB. My recruiter says just deal with it. I was originally supposed to be a Marine Security Guard but it got changed somehow? Did people at MEPS not put in correct information that I was supposed to be joining infantry? I’m currently just going to go with it but I’m a little concerned about this job program bs.
