[Koha] Patrons report errors

Hi, I am new to Koha and was trying to check on patrons reports. We seem to have no problems with catalging reports though. We have installed Koha 20.05 on Ubuntu lts 20.04. The error we get is: Software error: Can't call method "description" on an undefined value at /usr/share/koha/intranet/cgi-bin/reports/borrowers_stats.pl line 323.
