P.S. See if it is hard coded in the index or a table somehow. Not sure how that would work specifically.
Also I noticed that no locations on the west coast show up in the initial map displays. That usually indicates you do not have a large initial results setting at a high enough number . If your “enter at map” is not set to something else, it will default to center of US considered to be in OK. Assume Everett,WA is further than the initial display setting in miles. If you want to show there are locations everywhere on the West coast you might want to set that Results setting at 1500 miles.
Have you refreshed or cleared your cache to see if that clears out the deleted location?
