[Koha] Patron anonymization problem

[Andy Boze]

I'm getting ready to upgrade our Koha server to version 18.11.04.000. 
The server is set up and right now we're running it with a copy of our 
production database (which is currently on v 17.11).

When testing the batch patron anonymization, the response I get is that 
"0 patron's checkout histories will be anonymized". I used today's date 
as the cutoff. I ran a report on the old_issues table, and there are 
230 distinct users (not including, of course, the anonymous user).

I would assume that the batch anonymization tool would also report that 
there would be 230 checkout histories to be anonymized. It does report 
that number on our 17.11 production server.

I'm wondering whether someone might have an idea what could be wrong. 
I've checked Koha Bugzilla, but I don't see anything relevant there. Are 
others experiencing this issue?
