Map error - Jesmond

I have steadily been uploading kml's for Jesmond to try and map the whole area along with a range of photos from around the tracks there.

I have noticed that when I click on the link to the Jesmond map it zooms to the whole world and you have to zoom in about 20 times to see it:

This isn't the case for others:
Warners Bay (also mostly by me)

Glenrock:

All zoom into the map on arrival at the page.

Any reason for this?? Should I delete something and re-upload? If so what, I don't really want to re-edit all of them individually.
