Allow single word recipients for first line of address
Many labels are failing because of the delivery name not having a space in the middle.
Company names & department names fall foul of this and each time this happens we have to manually add an unwanted and confusing space in the middle of a company name. This is also true in the case that someone doesn't provide their second name
Just add a dot to either the first or second name section, we even sometimes add a dot to both when there is no name. You can hardly see the dot, it just looks like dirt :-)
