Deleting listings can be done from the listings view on an individual level and in bulk. If the listing that you delete in your Informed account gets downloaded again, it means that it is still active on your marketplace. In order for a listing to be permanently removed from your Informed account, you'll need to delete your listings directly on the marketplace first.
To Delete Listings One by One:
Go to your listings page.
Select the check box on the left-hand side of your listings for the ones you want to remove.
At the top of the page, you will then see the option to "Delete."
To Delete in Bulk:
Go to your listings page, and filter by "Deleted" status.
Click the check box in the top left of the listing table to highlight all of your items.
Next, click the green "Select All" button to make sure all items are included.
Lastly, click the "Delete" button at the top of the page to remove all items with a "deleted" status.
