I think this is some kind of a Redactor bug. This used to work just fine but within the last couple of Craft updates all of my words styled with the within a paragraph tag ends up unstyled with a "" before the words that were styled with with this tag when saved, when loading a saved Entry Redactor loads it this way. It seems to happen only to the second styled instances. I've contacted support but they didn't have an answer. I'm quite desperate to fix this as it's messing up our style guide Craft based site.
Here is an example shot.
