Diagnosis control by Number of Visits

Software Bahmni

The Bahmni document shows that number of diagnosis displayed on patient dashboard can be configured through number of visits. But that doesn’t seem to be working. Here’s my config

"diagnosis": {
                "translationKey": "DASHBOARD_TITLE_DIAGNOSIS_KEY",
                "type": "diagnosis",
                "showCertainty": true,
                "showOrder": true,
                "showDetailsButton": true,
                "displayOrder": 2,
                "numberOfVisits": 1,
                "dashboardConfig": {
                    "numberOfVisits": 1,
                    "title": null,
                    "groupByVisits": true
                }
            }

Also, I looked into controller, there seems to be no parameter like numberOfVisits like other controllers. Am I missing something?
