Hi @DaveH ,
Welcome to Text Blaze community.
It looks it is an issue with the page setting. Everytime you log into a different computer, it might be having a different URL.
While using a selector you would be shown the options for the page. You can select one of it as per your convenience.
If this does not solve the issue, please email us at support@blaze.today with the snippet contents and a video recording. So we can understand better what the issue is.
