I assumed this is the switchboard created by the built-in Switchboard
Manager.
Change the name of the Switchboard Items table to Switchboard
ItemsOld. Then create a new switchboard using the Manager. When done
save the new switchboard. Then Delete the new Switchboard Items table.
Rename the Switchboard Items Old to Switchboard Items.
