[Koha] Argument "0, 00" isn't numeric in numeric gt (>) at /usr/share/koha/lib/C4/Overdues.pm line 292.

[Michael Kuhn]

Hi

Our library is working with Koha 22.05.17.

Since some days the anacron job "cron.daily" sends us an e-mail with 
hundreds of lines like the following every day:

  Argument "0,00" isn't numeric in numeric gt (>) at 
/usr/share/koha/lib/C4/Overdues.pm line 292.

I see in the circulation and fine rules the "Overdue fines cap (amount)" 
shows as "0,00" instead of "0.00" as usual. However, this can't be 
changed at this place.

Changing lines in script "Overdues.pm" according to 
https://gomezcardozo.com/error-en-fines-koha/ didn't help.

How can this output be prevented?

Best wishes: Michael
