To see the groups on a conforming Figure you need to select one of the BODY PARTS - you currently have the main camera selected and not a body part. Remember when selecting things in Poser you need to select BOTH the figure (e.g: "Jersey" or "Figure 1") and then the body part where it currently says "Main Camera" under the preview window. Body parts have names like hip, adbomen, chest, etc. Do not just select the "Body" body part because that probably has no groups in it. In your new OBJ which is currently just a prop as far as Poser is concerned, the groups (if they are still present) will be available on the drop-down list which you will see at the top of the group editor. In your picture above, you can see the group called "Figure_8" in the list. Just click the little triangle near that and see if there are any oterh groups on the list.
