Why do components overlap ?

Hi, 

For some reasons most of the components overlap with each other. 

I have noticed different behaviours that seem to point out in the same direction : 

- When being pulled from the schematic into the layout, these components are placed very far away from the board outline. 

- Normally when selecting a component, a white-transparent rectangle shows the component, but for these, the rectangle is huge and is way bigger than the component itself

- When selecting the component using the View > PCB > Components side bar, the design is being zoomed out.

Anyone has an idea to redefine these components to avoid these problems ? 

Thanks, 

François
