Newly Added CI Attribute Not Showing in CMS UI

Hi,

I have added a new attribute to the CPU CI type - which is showing fine in the local client - but is not showing as a selectable attribute when creating a report in the CMS UI (although, it does show as an attribute when viewing CI properties).

Is there a delay in new attributes showing in the CMS UI - or do I need to do something else?

The new CI attribute properties are:
Attribute Name: Vendor_Processor_ID
Display Name: Vendor Processor ID
Attribute Type: Primitive (string)
Value Size: 50
Visible: true
CMS Browser Visible: true
Visible in preview mode: true
Properties group assignment: Additional

All other properties are blank/false.

We're using UCMDB version 23.4

Thanks in advance!
