Galaxy S9+ Google Calendar no longer works with Google Maps

[Android Central Question]

I have a Galaxy S9+ with the current OS 9. Recently Google Calendar has changed slightly. When I enter a location for a new event, it presents it slightly differently. It shows the name of the place then, below it, the address. And it shows a photo of it too. All this would be nice except when I click on the saved destination, Google Maps should come up automatically as the default navigation app. Instead I'm offered a choice between Citymapper and HERE; I can't select Google Maps at all. Yet if I go to an older event created on the phone, or a new one created in Outlook for PC (I sync between that and my phone), Google Maps launches as usual because the event is presented the old way.

Does anyone know how to fix this?
