我的标签的最后几行没有显示。我希望使用ScrollView小部件在屏幕上正确显示标签，但我尝试这样做，但是ScrollView不能正常工作，除非行数更多，但是随着行数的增加，当我再次滚动时，最后几行不能正确显示。简而言之，我想随着文本长度的增加，滚动视图可以正确显示标签的每一行，并且段落之间的间隔也不会显示
这是我的.kv文件的代码

A boy and a girl were playing together. The boy
had a collection of marbles. The girl has some
sweets with her. The boy told the girl that he
would give her all his marbles in exchange for the
sweets with her. The girl agreed.
The boy kept the most beautiful and the biggest
marbles with him and gave her the remaining marbles.
The girl gave him all her sweets as she promised.
That night the girl slept peacefully. But the boy
could not sleep as he kept wondering if the girl
has hidden some sweets from him the way he had
hidden the best marbles from her.
Moral of the Story :
If you do not give 100 percent in a relationship,
you will always kept doubting if the other person
has given her / his hundred percent. This is applicable
for any relationship like love, employee –
employer, friendship, family, countries, etc
and the most of the feelings we get now
days are just merely just the impact of the
surrounding now days we dont have a good
feeling that last long
and now we have to just name it in that way

我正在猜测您实际上想要BoxLayout的位置，但是我将按照以下方法操作：
