Hi Amine
Seems you have double clicked on the Infoobject, not the variable.
If you double click on the variable, it will give you the first screen. The second screen is from your infoobject.
When you double click on the infoobject, it gives you the option to restrict the same with any variables or individual values. As you could see from the second screenshot, the infoobject is showing that its already restricted to the variable and giving other options to choose from.
If you click on the drop down list, it will show you variables, single value, ranges, history and favorites.
Regards
Karthik
