Due to a restriction, mature content is generally disabled in the app. You have to enable it in your settings (https://picarto.tv/settings/app) first, to able to view them on your app.
Once you enabled mature content in-app, you have to re-log in in your app to load the new settings. Then you should be able to see your follows that have mature content.
