Accordion header has blank paragraph when configuring default block settings

Hi – thanks for the plugin, I’m using the accordion blocks throughout a new site and they work nicely. I found a little bug that I thought you’d want to know about. If I set some default configuration options for the accordion block (e.g. icon choice, body text colour, border width and border radius), the accordion headers get a blank paragraph inserted before the <h4> title, which pushes the title down below the header icon. I removed the configuration settings and it’s back to normal.
