Changing paragraph code to "

If I add the shortcode into a page or post all the formatting for the rest of the page or post changes.
<p> becomes ” and if I’ve used the visual editor and pressed enter to go to a new line none of these new lines work, so everything is bunched up running on the same lines.
I’m using a few other plugins and I don’t really want to disable them, I’m just going to look for another plugin but I thought you should know. If you want a list of plugins I’m using if it helps I will post them all.
