Cisco WLC 9800 software version not detected

Cisco 9800 WLC IOS version is not detected. Example:

Cisco IOS Software [Amsterdam], C9800 Software (C9800_IOSXE-K9), Version 17.3.5a, RELEASE SOFTWARE (fc2) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2022 by Cisco Systems, Inc. Compiled Mon 28-Feb-22 19:09 by mcpre

Please note the -K9 suffix to "_IOSXE" which does not match the regex at includes/polling/os/cisco.inc.php line 45. Should be trivial to fix I guess?
