Page with html table cannot be modified or deleted!

I am updating my site to WordPress. One of my old pages used an html table. I copied that table into a new page named ‘Papers’. The table had descriptions and links to PDF articles. I previewed the page, and it looked fine, so I moved on to another page. Later I went to open the ‘Papers’ page, and the only thing that came up was a blank white screen with a list of the PDF links and nothing else.

I couldn’t do anything with that, so I deleted the ‘Papers’ page altogether. I assumed the html table was the culprit. I decided I would not use a table. I created a new ‘Papers’ page. When I clicked on Edit with Elementor, the blank, white screen with the PDF links came up again. I tried several times to delete and recreate the ‘Papers’ page, but in each instance that blank screen with the list came up. I tried deleting the browser cache. That didn’t work. I tried using a different browser. That didn’t work. I am not using any caching plugins during development.

I could not make a new page called ‘Papers’ and edit it using Elementor. Elementor seems fixated on remembering that now deleted ‘Papers’ page and serving up my list of files on that blank screen.

Does anyone know how to solve this problem? It seems that ‘Papers’ page is cached somewhere within Elementor.

Thank you.
