On Page Load event fires only once

I am showing a list of documents in a ListView on Page A. Tapping a ListTile opens Page B, where documents can be edited.
After editing, the user returns to Page A.
Page A On Page Load event triggers a Refresh Database Request action which updates the ListView to show relevant changes to the document.

The issue is that the On Page Load event only fires the first time the user returns to Page A from Page B. The following times, the On Page Load doesn't trigger and the ListView widget is not updated.

I'm testing this in a FlutterFlow Test session in Chrome.

Thanks for any help!
