Problem with sub/child pages

Hi,

I created a subpage under the link read more… e.g.

Read more —>>> Subpage

But the problem I am having is that when I click the link I can see the text I typed ealier but the informations from the same page exists as well, I tried to delete it but I wont let me do that, the layers are not locked or hidden either:confused: how do I delete the existing info and enter new informations to my liking? I got the source files if you want to see. Here are some images:
