FS Listings and listings added via the control panel, either imported or manually are completely separate from FS listings. If you perform a search using the FS search functionality, none of your imported or manually added listings will appear in the results. Only listings linked to FS Client Accounts will appear in the results.
If you have your own listings you would like to add to your FS website, they must be added as if you were a customer.
The best way to do this, would be to create a custom internal package for you to use to add your listings. See this article on how to do this: /linkurealty-fs-system/adding-my-listings-to-a-fs-website
Otherwise, if the listing was added as a FS listing, then check the following:
Is the listing set to Active?
Is the zip code correct?
Is the account that the listing belongs to active?
Is the listing expired?
If your answer is NO to any of the above questions, then make those corrections and then try to view your listings again.
