To all who follow this topic:I have solved this problem with a simple way, which shows how it happend.
The way to solve this problem is to put cursor onto the bottom of the window and drag down, which will expand the window in the Y direction. Then, other options just appeared.
Besides, I found out that a lot of window would show uncorrectly with the size when it was first create. This is the most serious one which hide a important part and made it unable to use. While other windows like 'Clone card type' will show half of every line. Thus, I think it is necessary to provide warnings when abnormal window scaling results in display errors. Or, using a more simple way which is show window in a correct size which is large enough to avoid hiding some elements when it was created.
