CMS placing duplicate elements on a page

Anyone noticing that Weblfow CMS is acting strange? I am using the staging server and CMS elements are showing up twice on the page. But the navigator panel only shows one element?
This just started to happen?

I was able to find the problem. I was adding CMS collection lists to a CMS templates page and should not have done that. I think the CMS Collections element is only needed on static pages where a CMS Collection needs to be declared first (via the CMS Collections Element) and then the its list items can be connected to common elements in the static page. The CMS templates are already associated with a CMS collection, so the addition of the CMS Collection element was causing duplication. I removed the CMS collect elements and merely connected common elements to the CMS collection for that templates page.
