Missing Newsletter Smart Filter

Missing Newsletter Smart Filter

I had the 2 Smart Filters for Notifications and Newsletter, which I moved to subfolders under Inbox. After the move, nothing happens when I click on Newsletter (no contents show up), although Notifications still works. The description of Notifications is "Newsletters / Subscriptions / Automated Emails, - that sounds more like a Newsletter description, and the emails that are in there now look like what had been in the Newsletter folder. Now, everything that probably would have gone into Notifications is going directly to my Inbox. How do I get the two Smart Filters working again - I really don't care what they're called, I just want them to keep filtering out what they used to filter out.

Thank you!
