Hi. I updated a site that hadn’t been touched in ages, and one of the plug-ins caused a fatal error. I had to deactivate the plug-in and I am going to redesign those elements using X. However, they are showing up as “undefined elements” and I can’t figure out how to delete them. They don’t show up in the sidebar when I click on them. 
There are quite a few of them and I would like to delete them all.
Thanks for the help.
