If you type text in the Find Your Destination popup and click Apply without selecting a suggestion, the destinations page can open with no filter applied. This is corrected in HomeRunner Toolkit 3.249.0.
After you update, clicking Apply on typed text works this way. If the text matches a resort, island, or city, that destination is applied as a filter. If the text matches no known destination, it is used as a property-name filter on the results page and appears in quotes in the Where field.
The Start Over button clears the filter.
