Forum:Undo removing references and HTML tags

For some reason ever since yesterday when I try to undo an edit not just the last edit is undone, all the references and other HTML tags are removed as well. This makes it where I can't just hit "Undo", I have to bring up the article version before the one I'm trying to undo and edit and publish it. I checked a few wikis and it is only happening on this one. I've tried clearing my cache, logging out, and using a different browser but that didn't help.
