Seems you are trying to make a group and no device seems to be matching the criteria to be a part of that group.
In Screenshot 1 there is a mistake, that whatever rules you want to make, you need to click Add Rule Expression for that to be added, unless which it is useless.
For more details on managing/ administering group and grouping policies, please check the user guide section :
