Municipalities Disappear When Doing a Search

My municipalities disappear when I am entering in search criteria on different tabs when I click the back button.

Do not use your browser Back button when using FlexMLS. If you need to go back to the previous tab to add/change the search criteria, click on the tab name instead of using the browser back button.

If you need to go back to add/change search criteria from the Search Results screen, click on the Edit Search tab and then onto the tab/section that you want to change or enter criteria for.
