How to properly use the Bar Value options in the Campaign Settings?

I've tried googling this and looked at previous threads asking the same thing, but the methods didn't seem to be working for me. I assume it will automatically set the bar to show the (in this case) HP of the creatures I drag onto the map, however I couldn't get it to work. Here's how I have the settings configured right now.   But when I drag the creatures in question into the map, they have no bars, and looking into them the bars don't have values anywhere. I've pulled them from the compendium to do this. They are fresh stat blocks I haven't edited. Can anyone help me with this, please?

I think those values only apply for characters from the Compendium, and it will only apply to those created after you set the settings.
