Since I do not know what you are doing, I can't tell you what you are doing wrong.

As has been said, it’s not always easy to advise where someone is going wrong when potential helpers don’t know what you have done.
If you click the image below, you will see a short video of how I have created name labels and might help you out.
My source for the names is a created Address list (Excel .csv file) with the relevant names and addresses.
In my example, I have removed the addresses during the process as they are not needed (especially on a name label).



Labels should always be scrutinised before printing as long names or names with double barrel surnames may not always show correctly until the formatting is addressed.

Note: The names and address in my example are fictitious and don't actually exist.
