Problems with RG when scaling the page

I have a RG for five cells and a “full list” http://joxi.ru/82QPpBWi9KRBEm. If you increase the screen resolution of the monitor, then the RG is stretched. but the cells are not stretched at the same time http://joxi.ru/GrqndjVcGw6ZKm. If you put in the RG “Fixed number of sell” http://joxi.ru/GrqndjVcGw6LKm then it simply draws the sixth cell although there should be five of them http://joxi.ru/l2ZPn43i7Be4Or. How to make cells in RG stretch together with RG?
