CommonUI navigation bug in MenuSystemPro (buttons snap to center after scaling)

Using the MenuSystemPro template by Moonville, I noticed an issue with gamepad navigation in a CommonUI ActivatableWidget.

  • WBP_KeyBinder widget has 3 horizontal buttons → navigation with gamepad works fine at default size.

  • If the button container is scaled or takes more than 50% of parent HorizontalBox, navigation always snaps to the middle button instead of moving up/down correctly.

  • Same issue if the HBox is at the root and occupies 100% of the space.

  • On Moonville’s side (Asked to the creators on Discord), it works fine.

  • Tried changing DPI settings but the behavior persists.

Expected: Up/Down should move normaly inside the keybinder grid
Actual: Navigation defaults to the center button once Hbox is scaled beyond ~50%.

Possible Cause / Workarounds Tried:

  • Could be related to DPI scaling or higher-level container geometry.

  • Behavior not fixed by adjusting DPI settings.

  • Works fine for others in the template → suggests something setup-specific.

  • Haven’t yet found a way around it besides setting explicit navigation rules per button.

So did anyone encountered this same issue and found a fix?
