PDF showing text not added in Illustrator
I am working on an old menu, and way before in the beginning it had a certain text, but with time I upgraded and deleted that other text. Now, working on it again I do some little changes on the text and when I save it to a pdf, the pdf has that old text from months ago on top of some words that I have on the menu. On Illustrator it does not show it at all, I even tried selecting something, but there is nothing there. Yet when I save and open it in PDF, it appears. I do not know why. Does anybody know? I have attached pictures with captions. In advance, I appreciate the help. Thank you.
