Extra Tags

For some reason there seems to be a set of extra tags being put into the body of my content. I think this is related to information I have pasted in.

I will copy the text from another website and past it in. It seems to have converted the text fine, looks the same as the other site. I have it on full HTML but I get this extra p, span, and br tag.

i attached some images that show the extra code I am getting. It does not seem to be completely consistent. Looking for anyone who has a similar problem.
