Hello Adam,
In your schematic check the properties of the pcell symbols, the properties of pcell symbols will give you the location of the libraries that are being used in your design. Then go to that library and check whether there any layouts that have been created for that particular pcell symbol. If they are created then come to your layout editor and fill up the edit properties form for your pcell symbols with layout in the view option. This will change your pcell symbols to pcell layouts. But if they do not exist then you check for other libraries available in your library manager for your pcell layouts or need to create your own layouts.
In Layout Editor select the symbol and in menu bar go to: Edit ---> Properties or bindkey for that is " q", you will get a form and there you can change the properties.
shift f & ctrl f are are display icons only for viewing the hierarchy of layouts in a design.
Hope this helps you.
