A confusing icon on SAnd 's UI

Hello, I found a problem with the app's UI design. When I first saw this widget in the upper right corner, I thought it might be related to data transmission. After clicking on this widget, I learned that it is used to set the real height. Although the widget has two arrows pointing up and down, which seem to be related to height, I was confused by this widget when I used it for the first time. So, for better user experience, could you fix this issue?
