Are you 100% sure that you completed OLCI for your wife? Did you receive the OLCI email confirmation? If so, nothing to worry about. If not, likely that she isn't checked in.
If you go back into the booking, and select OLCI, what does it say against her booking - "already checked in"? If so, again nothing to worry about. In which case you should have the options to P/F/EM her BP.
If it says "check-in unavailable", then likely she is not checked in.
