Using EE 2.5.2 and Blueprints 2.0
Note: Before installing 2.0, I had Blueprints 1.x enabled but I wasn’t using it. I uninstalled completely before uploading 2.0 files and then re-installed the extension.

I have attached a screenshot of my settings.
You will notice there are 2 Publish Layouts I have set up. Both are assigned to the same template file, but have different thumbnails. I desire to have different publish layouts for each thumbnail where different fields are shown and hidden. The pages these layouts would be applied to are in the same channel (the “Pages” channel).

If you look at the second screenshot, you will see that only ONE publish layout shows up in the structure tab and the thumbnail doesn’t show, so I can’t select it. I verified that the thumbnails have been successfully uploaded and can be seen in the filemanager or Assets (you can see them in screenshot 1 from the Blueprint settings).

Finally, when I try to save a layout for an entry, I have no member groups selected and I select the layout I want to assign (for example, “Default,” but when I submit the entry, then I open it back up to check, the layout isn’t saved. Expanding the toolbar reveals that no layout is checked, so it seems that it is simply not saving my layouts.
