How do I remove white gaps (seen on print-ready PDF) in between two pages?

Hi all,

I need an urgent response to this!!

I am trying to make my brochure print ready. The printer asked me to put bleed on all four sides of every page which I believe I have done?

But have a look here and see the annoying overlap of pencil image onto the left page (printer says to add bleed to all 4 sides of the right side page below):

and this unwanted white gap inbetween these two pages:

THIS IS HOW BOTH EXAMPLES SHOULD LOOK (Preview mode on InDesign):

Thank you in advance!
