Sizing in columns is not arranged on the design screen

I cannot arrange columns in the design because they will be above the others and it is not tidy as the classic Android.
Please, see this problem coz I cannot arrange my components in the columns in the design screen. They are above each others.
Whether I set columns in Absolute size or Relative size, they are mixed above each others.

Can you show a screenshot? Without it, it’s hard for me to understand what you can not do.
