If an asset or group of assets policy id(s) were verified after the asset(s) were listed for sale on the marketplace, the "Verified" badge will not be latched.

You can correct this by visiting "My Sales", locate the listed asset(s) in question and select "Unpublish Sale". 

The listing will now be placed in a semi-draft state, where you can enter it via "Setup/Edit" from "My Sales". 

Simply select "Update Draft" at the bottom of the window and proceed with re-publishing the sale. Your asset will now have the "Verified" badge latch to the asset(s) with newly verified policy id(s).
