The issue is originating from your web host / CMS - Gixxy. This conclusion is based on several tests we've done: on the view itself and the 4 major CMS (Joomla, WordPress.com, Weebly, & New Google Sites).
Embedded view disappears in Gixxy when a search term cannot be found.
As you can see on the screencast below, the Table view remains intact (on the 4 major CMS tested) even if there's no entry found. The problem only happens when the view is embedded in Gixxy.
Please reach out directly to the Gixxy Support team to have this issue investigated.
You can use other CMS or website builders as an alternative.
