Hey @MadOregano and welcome to the community!
You have to set the item prefixes in the page configuration.
Based on your explanation I would assume that you’ ve tried to set the properties in the widget-editor (in which the set properties will not be saved).
To do it via page config:
Click on Edit in the top right corner of the page you want to add the widget to. Then Add Block → Add Row → Add Column → + (Add) → Select the widget → Click the black square icon on the top right of the widget and select Configure Widget → Set-up the widget to your liking → Hit Save in the widget as well as on the page and it should work! 
P.S. If you want the widget to be smaller in width or if it should be resized based of the browser-size, you could do this via the Column Options in the same menu.
Don’t hesitate to ask, if you need further help!
