InDesign color space difference

ok, honestly, i'm not sure how explain this, let's give go.

 

i have 1 indesign project, portrait a4 booklet, , in addition project, want have landscape a4 booklet.

 

so, i've been working on portrait a4 booklet few days , colors they're supposed to.

and today started working on landscape a4 booklet, imported same background used in portrait document, but, colors totally different....

 

in portrait one, dark gray/black/white looks normal, in landscape project, background colors more red toned...

 

i had @ color settings make sure i'm using same color space both projects:

 

 

the normal one                                      reddish one

 

 

when exporting, both of them same, it's working space different, , it's annoying. , want make sure end result same, no matter what, sending these printed company.

 

 

does have clue why happening?

 

 

thanks in advance!

is transparency blend space same in both docs?
