Hi Anna
At this time you would need to use the "Edit and Relist" tool for each individual item. On the Closed Listings page, when you use the the Edit & Relist tool (the arrow and pencil button) you'll be able to remove the template and upon relist you'll get the active content-free Scrolling Gallery & View Counter.
If you're listings only need to have the Scrolling Gallery updated, you can contact our Customer Support Team and they'll be able to upgrade the Scrolling Gallery within your active listings. But if you need to remove the template and/or upgrade to the View Counter you will need to use the Edit and Relist tool.
Best,
Natasha
