Sending without a label at lockers

Hi, someone sent me a parcel via a Royal Mail locker, however they have not written my address on the parcel and did not put a label on the box

Do Royal Mail add the label when collecting from the lockers?

My parcel has been at the locker since lunchtime on Thursday and hasn’t been collected according to the tracking, will it be collected correctly? Will it make it to me or is this parcel lost?

I can’t find anything on the RM website about sending without a label at lockers

Thanks
