Moved my library, now all products are marked as "NEW"

Title explains the situation, I recently moved my library from my internal hard drive to an external drive to free up space, following along with a tutorial that I found on this forum, which included a step where I re-import metadata. Now every single product in my DS library is marked with a blue box and a "NEW" tag in the corner. This goes away when I click on the item, but I'm not gonna go through and click every single item and right now it's pretty visually annoying. Any way to get rid of all the NEW tags?

To remove products/assets from the "New" group, multi-select all of the products/assets that you want to change, right click one of them and choose one of "Group Products As > None" or "Group Products & Assets As > None" or "Group Assets As > None"
