Name field getting auto-populated with odd values

[Manaus]

When I create a new page in the admin environment, the name field gets from somewhere a value like 2017-08-03-312631thursdayamerica-new_york, which is cool, but I'd like to enter the page title first. This default function seems somehow deactivated.

Since it is a fairly old website (2.7.x), I can't recall if I set that up, or it's some sort of plugin/function.

Thank for any suggestion

See if the template's "Name format for children" field is setup to output a date (Family tab)
