Bug when exporting for development : deformation of some pages

Hello,

I have a problem when I export my pages for development, some pages are distorted.

A large part of the top of the page is cut off and the page is distorted in height.

I don't have this problem when exporting for review.

I have 26 screens (1/3 desktop, 1/3 tablet, 1/3 mobile) and that only makes me that for 3 of my mobile screens.

EDIT : These are my 3 models the biggest in terms of scroll (H: 8220 to 10381). The problem seems to appear when the models are more than 8000px high, how to fix it?

Top of the page in review version:

Top of the page in development version: (When I click where there should be the header the purple outline is displayed well it is as if the whole model was behind a distorted image)

Overview in the software :

I tried everything, duplicate the models and delete the old ones, put the links back, make several exports, restart the software...

Thank you in advance for your help.
