Unable to configure settings to exclude items from A/V scans

Norton Internet Security v22.9.1.12 installed in Windows 7 Professional.

I am trying to exclude a folder from being scanned...

I click the "Settings" tab at the top of the main menu, opening the Settings Menu. I click on "Antivirus" to open that sub menu then click on the "Scans and Risks" tab at the top of that page.

Scrolling down the page to Exclusions / Low Risks, I find "Items to Exclude from Scans" and "Items to Exclude from Auto-Protect, Sonar, and Download Intelligence Detection."

When I click on the blue text "Configure [+]" that is located at the right side of those topics, nothing happens - no selection menu opens, nada, the links are not active.

Have they been disabled by another setting that I am not aware of, or am I doing something wrong here ?

Need some guidance please.
