Patch 25a: Since implementing this in a Test Environment, we have lost some functionality.

Summary:

It has been brought to my attention that when someone raises a Help Desk Request we have encountered an error.

In our current live environment, we have no issues, but since the implementation of Patch 25a in our test environment, it has occurred repeatedly for multiple users.

Originally if someone was to raise a request they would select their relevant subject and the category would match accordingly.
However, after Patch 25a, the category no longer matches. It instead provides a reference number.

Example -

Previous Summary:
Subject - Advice = Category - Advice

Current Summary:
Subject - Advice = Category - 300002768956847

Any input would be greatly appreciated.
