I don't know about the custom codes in the plugin. But you're in touch with the developer. He would be the best resource. I was just trying to solve your initial problem and didn't look at the custom codes.
Your banner problem is strange to me. I look at the code and it's got backslashes in it.

I can't figure out where this is coming from. I'm going to ask the team to take a look since I haven't encountered this before.
Have you looked at the article and do you have any short code in it that should be deleted?
