Add Waypoint not working in CarPlay

While en route in a multi-stop route, the Add Waypoint button is only searching for charging stations, and it is not searching for coffee shops, restaurants or washrooms, whether searching by name or using the category buttons. If I press the Add Waypoint button to try searching for a coffee shop, it only searches charging stations. This happens on CarPlay in a 2024 Honda Prologue connected to an iPhone 15 ProMax running iOS 26.6.1.
