[Koha] Circulation checkout date incorrectly set

[Bob Birchall]

A school in Sydney has a circulation rule for staff and numerous rules 
for various categories of students.  The default rule takes the (much 
longer) staff issue period.

When checking out to a student, the return date is set to the date 
calculated from the default rule.  That is, the rule for the specific 
patron category seems to be ignored.

Koha 3.02.02; circ rules, sys prefs, calendar and patron records all 
appear to be in order.  Nothing in the koha log.

Has anyone seen this behaviour?

Many thanks,
Bob Birchall
