Deleting table's sample items is not removing all the data

Hello again Yisrael… still having an issue.

I created a new, standard (not-dynamic) version of the page and the new table on the new page is STILL displaying sample data from when I initially added the table to the page. If you go to manage items , it will not allow you to delete all the items. It insists that at least ONE field (column) be defined.

And beyond that, and this is bizarre: I left the default column for PROFILE PIC as the only remaining column… but when you browse to the page, it shows the sample data from the EMAIL column, which I have deleted! This is a completely new page with a newly-defined table. No copy / paste.

Lastly, my search code stopped working on the standard page. It still works on the dynamic version.

Here’s the NEW, standard page

Here’s the original dynamic version of the page - with a functioning search feature (search for Brussel, please).

**How can I get rid of the old-sample-data that is being displayed before the visitor searches. ** It is so unprofessional. I would LOVE to make it work on the DYNAMIC version, since my search works on that page.

I appreciate immensely any assistance. Thank you kindly! Cynthia-
