UI Panels are not positioning themselves according to screen size

My UI elements inside my panels are scaling fine with screen size, but the distance between my different panels is not. I have 3 panels in my scene at different relative position which i set at 1920x1080 reference resolution, and switching between them using animation. But when i change the game view resolution, these panels do not align themselves right. Here are the screenshots:

These are the panels at 1920x1080 which i set.

These are the panels when i set game view resolution to 2340x1080. As you can see, the "settings" panel is still fine but the "more settings" panel does not repositioned correctly.

The same thing happens when i set game resolution to 800x480.

Please help me..
