Deleting PDF line between 2 sites

[Salome5C2A]

I need your help 🙂
I have created a brochure in InDesign and saved it as a PDF for clients to watch. I want this PDF to be displayed without these lines in the middle. So that images can be seen throughout without a dividing line in the middle of the double site. Here a picture to see what i exactly mean. Thank you in advance! Wish you a nice day.

This dotted line shows the page limit. You can't remove it.

If you don't want it to appear then you need to combine those two pages to a single one.
