2 urls for the same web page

HI Prismic Team and Community !

We have a little problem.
We have 2 urls pour the same destination page :

Attached screenshot : The page created 7 months ago had been modified but it seems that there are two urls.

The second url should not exist.
May be a cache issue?
Can you help us please?
Thanks a lot.
All the best,


Hey Team,

This is a UID history issue, this and the solution are discussed further here:
