Why can't I produce more than one sheet of labels at a time?

I have the database registered. I can get my label sheet up and insert data but only one sheet at a time using “data to fields”. Mail merge doesn’t seem to work at all. I’m now on version 5.3.6.1

I’ve come to the conclusion that either the function has changed so much that none of the available instructions apply anymore or in the current versions of LibO the mail merge function is broken.
I can perform Mail Merge in LO 3.6 with no problem
