Deleted Panels Keep Showing Up

Using 4.6.3 and still very new to it. Was set up by a previous colleague…

Anyway, I duplicated a panel initially to play with alert settings. Got it working, but after I saved the dashboard, presumably with the one extra panel I had duplicated, I somehow ended up with 14 extra panels, all duplicates of the new panel, along with its alert settings. And when I delete the extra panels and save the dashboard, they come right back after a page refresh. Any thoughts would be appreciated.

Here’s a screenshot:

Nobody? Bueller?

Another note is that all the extra panels appear to be sending alerts separately. Got about 1000 messages last night.

Probably an issue with panel id’s. Please verify that all panel id’s are unique in the dashboard json model.
