Предварительный просмотр Android Studio перепутан, и просмотры с непоследовательными полями

Question

Почему Android Studio Preview так запутан по сравнению с реальным приложением?Одно из представлений вылетает в угол, несмотря на ограничения в каждом измерении.

Вторая / третья часть моего вопроса: почему в моем приложении большой разрыв между вторым делителем, "divider2" и нижнимНазвание блока 1?А также, почему существует большая разница между настройками модуля 2 и вторым делителем?Раньше там было поле в 30 пикселей, но теперь его нет, поэтому его не должно быть.

Дополнительная диагностическая информация: если вы удалите app: layout_constraintHeight_max = "40dp" из обоих элементов unit2SpecialMod и unit2ShieldsUps,тогда превью будет выглядеть как само приложение.

Кроме того, четвертая часть: почему в предварительном просмотре поля действительно правильные, несмотря на то, что представление брошено в угол, по крайней мере, перед удалением этой строки, и почему они становятся неправильными, как показано в реальном приложении,как только вы удалите эту строку?

Скриншоты:

Это скриншот реального приложения, и вы можете увидеть странные поля

Это скриншотпредварительный просмотр студии android, и вы можете увидеть странный вид в углу, который является Unit 2 Special Mod, "unit2SpecialMod"

И это рассматриваемый XML-файл, он довольно длинный:
