I have had several issues when I add different blocks into a stack. In this case as can be seen in the attached shot, 2 Sidebar Navs were meant to be separated by another block type - in this case a button marked "Our News".

What happens is that the button has got included inside the top nav item of the block below it. If I were to hover over the "About us" item the whole grey area turns into its hover colour. It's like it has got included within the <div>...</div> tags.

The only block type I could managed to insert into the stack that didn't encroach into objects atop and below it was a Content block, carefully crafted.

Is this something others have come across?

thanks

Robert
