How do I add a Newsletter block to a page section using the Brine template?

I'm trying to add a newsletter block to a section of a page, but it doesn't insert it.  All it does is bring up the settings of the block in a popup window.  But the block never appears.  I do notice that it readily appears in the footer, however.  

Is the Newsletter block in Brine only for the footer?

Shouldn't be. I added a newsletter block to a full page, a section of a page using Basil, a member of the Brine Family. I click on Newsletter, the settings come up and I hit save in the top left corner of the block where I want it. I also added it to a section of an index page in Brine as well. 

I've tried it in two browsers, and it still doesn't add a newsletter block.  Attached is a screenshot of what I see when I click on the Newsletter block.  It brings up the popup as you can see, but it doesn't insert anything into the section, nor does it have a "Save" button.

By the way, there already is a Newsletter block on the site in the footer.  Is it possible that there can only be one instance of the Newsletter?

That had not occured to me. I will find out.

I posted two newsletter blocks on the same page of the Basil template. I see no reason it would be different than the Brine template since they are in the same family. Something else is going on here. 

The Newsletter block on the site appears to be broken.  I realized today that I can't edit the existing one in the footer either.  It results in an error when I try to save a change.  The error has no specifics to it though.

And just to clarify, the Newsletter block is only on the homepage footer, nowhere else because I can't put it anywhere else.  So, it's more or less stuck there as is.
