I've got an odd circumstance where a WYSIWYG block is not able to be removed from 2 pages created with the Pages app. I delete them from the page using the block editor and they appear to be gone. However, when I refresh the page, the deleted block is restored. 

Any thoughts?

Also, if I add an additional block (not a WYSIWYG block) and then refresh the first "rogue" WYSIWYG block described above duplicates on the page. Creating a new page also shows the "rogue" block on the page, even before any content is added.
