My problem is: Contacts are being created with their Name set to the landing page URL whenever they view a landing page after clicking a Facebook Ad. We have about 90 of these contacts. But the landing page shows it only has 1 hit.

I think ad is somehow triggering some kind of form submission which mautic tracking script (mtc.js) is picking up as contact.

Inspect requests that are happening to your mautic instance from this landing page. See what mtc.js is sending back to Mautic and try to ensure send event is triggered on actual form submission.
