<p><br></p> being entered from Summernote

I have an insert form that adds info to DB with Summernote. If the summernote field is left empty it adds <p><br></p> to the database. I need this to be null or empty.

On the detail page I have a dmx-hide: that isn’t hiding because the field is not empty.

So do I format my input into the insert statement so that it removes it there? Or do I use a condition on my show/hide field that doesn’t show if table value = <p><br></p>
