Labels populates table cells with database field names, not addresses

I want to print mailing address labels. Following the instructions as best i can tell, which are two largely similar versions of the same process:
https://help.libreoffice.org/Common/Creating_and_Printing_Labels_and_Business_Cards
https://help.libreoffice.org/Common/Printing_Address_Labels

When I click New Document, I get an .odt page full of 30 tables perfect for printing on labels, but the contents of each table is the spreadsheet column title/database field name, repeated 30 times, instead of 30 names/addresses, like this with a gray background:

For some reason Address in brackets isn’t appearing above. I’m able to print a sheet of my return addresses no problem.

What do i need to do?

Please test with the option Menu/View/Field names

ok this is how it copy/pastes, but it does not look like this on my display:

This is how it looks:
Branch Mailing Address Labels.Sheet1.Name
Branch Mailing Address Labels.Sheet1.Address
Branch Mailing Address Labels.Sheet1.City [and so on]

This is what shows in Inscription Label text, transferred after selecting the Database and Table and Database field and then the Left Arrow:

<Branch Mailing Address Labels.Sheet1.

to confirm; what i copy/pasted above that looks like the 2nd paragraph above is what shows in View > Fieldnames

Did this ever get resolved? If so, how? I am having the exact same problem

I would like to add to this also. I have the exact same problem. It happened to me on version 5, and I am on 6.1.4.2 now, and the issue is the same.

And this thread answered it for me:

If you have the database already setup for the labels, and do File > New > Labels, and have already selected your database source, when you click “New Document”, there is an additional step.

You must do a mail merge Tools > Mail Merge and click Next, then Finish. This brings up a button toward the top of the window that says “Edit individual documents”.

From there, it’ll create a new document with the data populated from the database, using the template you just created.
