Please note that if you choose the One particular <your module> only ...
option, you will be able to select only one item to be displayed in details view.
If you would like for example to display two particular module items on a page, one of the options I can suggest is to drop your module's widget two times on this page and configure the widgets to display the desired items.
Another option is to use the Selection of <your modules>:
option which will enable you to filter the displayed items by dates or by classification. In order to filter the items by classification, you first need to add the classification as a custom field to the content type. Please refer to the attached screenshot for more details on this.
