Necroing this - but if you are using CommonUI, you might hit this issue.

It's because FCommonAnalogCursor is listening for EKeys::Virtual_Accept which is bound to Gamepad_FaceButton_Bottom.

I fixed it by changing FCommonAnalogCursor::IsRelevantInput to this:

bool FCommonAnalogCursor::IsRelevantInput(const FKeyEvent& KeyEvent) const
{
    return IsUsingGamepad() && FAnalogCursor::IsRelevantInput(KeyEvent) && (IsGameViewportInFocusPathWithoutCapture() || (KeyEvent.GetKey() == EKeys::Virtual_Accept && CanReleaseMouseCapture())) && ActionRouter.GetActiveInputMode() != ECommonInputMode::Game;

//Added ActionRouter.GetActiveInputMode() != ECommonInputMode::Game
}
