The design options are confusing, especially since I think there is a lot of mismatch between what appears in the Design Option properties panel for the Slide vs the Block.

1. Add a new Conversation Slide
2. Look at the Design Options for that slide. There are four. The first (upper-left) has a green background. The second (upper-right) has the speech cards appear at the very bottom of the images.
3. Click on the Block itself
4. Look at the Design Options for the block. There are also four. I suspect the are supposed to completely correspond with the design options for the slide. But the images are completely different! The image on the Upper-left does not have a green background. The image on the upper-right shows a different speech block which is not possible to achieve. Clicking on either the upper-left or upper-right design options presents the items as are demonstrated for the slide itself and does not correspond to the preview for the block.

What is the expected behavior for design options for slide vs block in this case? Why don't they match? Why doesn't the Design Options for the block behave as it's properties panel looks?
