UEFN updating stats in nested UI Widgets

I am hoping to display multiple stats onscreen in one parent UI widget via existing creative devices alone (not Verse).

Expected: I created a parent UI widget that embeds a Stat-bound UI widget…I expect that the Parent UI widget will display the updated stat info from the Stat Device widget.

Actually: Parent UI widget does not show stat updates.

Let’s call these “Parent HUD UI Widget” and “Stat UI Widget”.

I created a custom UI widget to display a stat (“Stat UI Widget”). It shows stat updates when assigned to the Stat Creator’s “User Widget” and properly bound.

I then embedded this UI widget in a parent UI widget (“Parent HUD UI Widget”) that is designed to display multiple stats together.

If both of these are on-screen (the Parent HUD UI Widget via a HUD Message device, and via the “Stat Bar Shown in HUD” property on in the Stat Creator device), the one linked to the Stat Creator device displays stat updates as expected, but the one that is displayed via the HUD Message device does not update.

I have also tried assigning the “Parent HUD UI Widget” to the Stat Creator’s User Widget property, and this also does not update.

I’ve included screenshots of the UI editor for both of these widgets for reference.

Also, I’ve noted that the Parent HUD UI Widget bindings shows the Image widgets and Named Slot widgets from the child, but not Text Block widgets. I set bindings for the child image widgets in the parent UI bindings, but these do not work (I’ve attached a pic showing the child Stat UI Widget image properties in the bindings menu of the Parent HUD UI widget).

Am I going about this wrong? Or is this a known issue? Any help would be greatly appreciated.

BTW, I’m trying to achieve this with existing devices as I’m teaching a course that doesn’t cover Verse.
