Accidentally duplicated "Default View" a dozen times?

This is a stupid noob mistake, but I can’t find the solution with my searches.
Basically I hit some button or command and instead of the normal “Default, Nodes, UV Map” views, I created about a dozen extra duplicates of the “default” view on that list. I’m not sure what I did or how to delete the extras.

Select the scene and press the X button to delete
