Missing Showcases

When I click on NY Upstate Showcases it shows (76) but only 58 come up. Where are the other 18 Showcases.

Its a good possibility that they are not showing because the provider has not logged on in a while. When they do not log on for a period of 90 days, they drop from verified provider status. When that happens the showcase will be hidden from view.

Thank You for the quick ans.
