problem adding image to an unit

Hi i have just purchased Cousepress PRO and im testing it on my site.
The issu is that i cant add an image from an url if it isnt inside page 1 in na certain unit.
I know this is strange but when i add an image through add media button in the page 1 of an unit it works fine, but when i do the same in page 2 or page 3 it just doesnt insert any image in the visual editor box. Can you help me fixing that?
