500 error when editing template

[mindrb]

While editing some templates my colleagues encountered 500 error. Which I can see in error log:
[Wed Jul 26 09:06:38.785085 2023] [php:error] [pid 13250] [client 172.16.1.1:52344] PHP Fatal error: Uncaught PDOException: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'CDUTemplateID' in 'field list' in /var/www/html/classes/CDUTemplate. class.php:218\nStack trace:\n#0 /var/www/html/classes/CDUTemplate.class.php(218): PDO->query()\n#1 /var/www/html/classes/DeviceTemplate.class.php(206): CDUTemplate->DeleteTemplate()\n#2 /var/www/html/device_templates.php(271): DeviceTemplate->UpdateTemp late()\n#3 {main}\n thrown in /var/www/html/classes/CDUTemplate.class.php on line 218, referer: http://dcim.int.bite.lt/device_templates.php?TemplateID=56

Quick grep through code shows that line in ./classes/CDUTemplate.class.php is:
$sql="UPDATE fac_PowerDistribution SET CDUTemplateID=0 WHERE TemplateID=$this->TemplateID;";
Should not it be?
$sql="UPDATE fac_PowerDistribution SET TemplateID=0 WHERE TemplateID=$this->TemplateID;";
There is no CDUTemplateID column in that table but TemplateID is.
