List has an empty map

[+===sgb]

So I do a search ( as it happens for Church Micro caches within 25km of the southern tip of the Isle of Wight). The list looks good, the map looks good.

I save them to a bookmark list and then go and check the list, renaming it from CM_IOW to CMs_IOW.

The list is fine.

Then I view the map of the list and it is empty and is based on my home location.

 

What is going on? How do I see the map of the bookmark list?

I retried it a few hours later and it worked fine. STRANGE.
