I cannot click the "Confirm Condition Does Not Exist" checkboxes in Cleansing CAT?

The "Confirm condition does not exist" check boxes allows the clinician to review chronic disease patients in cleansing CAT.

In order for this to be active, the practice needs to have Topbar installed at the practice. 

The reason is that the information is stored in the Topbar database.
