[Koha] Records missing from data export

[David Liddle]

My further investigation into the matter seems to indicate that it is my
analytic records that are not being exported. These were created using the
Analytics Enhanced Workflow method described in the manual. Does anyone
have an explanation for the situation?

The pre-production server that I am working with is running Koha 3.20.04 on
Ubuntu 14.04.3 LTS.
