How to keep widget out of the black bar?

Unexpected result. The child widget stays on the black bar after the resize.

Expected result like in Lyra’s. Widget stays in game screen.

Hi guys, when resizing window, does anyone know how to keeps the widget on the game screen and not have it get on the black bar when my game camera is set to Constrain Aspect Ratio.

I set my widget up the same as W_ShooterHUDLayout , the widget is also derived from CommonActivatableWidget like of Lyra’s. The anchor of my child widget is also setup the same as with Lyra’s Healthbar in the picture.
