Store Locator for WordPress has the option to cache the store’s data, so in some cases, users’ newly applied changes are not reflected on the frontend that they have made on the backend, in that case, first of all, please make sure that the cache is not enabled, the status of it can be seen through the ASL Dashboard.
In the above screenshot, two language data files are cached to serve them in speed, to turn off or refresh the cache, go to the ASL Settings, Manage JSON Cache section and turn off the switch or refresh them by increasing the version number.
