Error message when clicking on Client Registration 'The reference to entity "sysparm_category" must end with the ';' delimiter.'

Hi all - long time listener, first time caller.

I'm running into this message again, it first popped up in vRA 7.2, and then recently resurfaced in vRA 7.3. The message occurs after importing the XML file and committing the update set, and then attempting to configure the OAUTH settings under basic configurations.

Version 7.3.0 build 5604410

ServiceNow Jarkarta3.0

Version of the ITSM plugin - 3.0

Thanks in advance!
