[Koha] items.fine is zero although fines are calculated

Hello, I have a strange problem: Fines are calculated and shown in the fines tab of a user, but in our overdue notice (email) fines are 0.00. We use <<items.fine>> in our template and it worked till our upgrade to 19.05. Is items.fine deprecated or did I miss something? Our Koha version: 19.05.02.000 Best Regards, Stephan
