Item for "Hilton.com" showing out of order at top of Item List in Title order

This is not Mac-specific. It also occurs in the iOS app and Chrome extension.

When sorting by Title, it looks like titles with numbers should show first ("#" section"), followed by alphabetical order.

But for some reason "Hilton.com" is showing at the top with titles that start with a number.

What would cause this to occur?
