Layout grid shift using Blurb plugin

[Edward301212859g3b]

I'm in the final design stage of a 100 page book. I'm using the Blurb template in InDesign. I added a few pages to the front of the book without a "parent" so not to have page numbers. When I went back to the layout the bulk of the book - including all type and pictures - were shifted about 8 points to the left on all the spreads except the new pages. Some going out of the gray (safe printable area) Blub has in its template. I could manually move all content but I'm not sure this will resolve. My concern is objects beyond the gray box could be trimmed out. It seems like a glitch but I can't figure out how to get back to all pages showing correctly. I looked at "margins and guides", as a test put in new margins but the gray box is still not aligned. Maybe the attached photos will better explain my dilemma. You will see the gray box outside of the safe grid area supplied by Blurb. Thanks in advance for any insights. Ed

Was the number of pages you added odd or even?

odd, 5 pages at the beginning. those are accurately on the grid, the balance of the content is shifted left and off the grid. thanks.

Adding an odd numberr of pages makes all the other pages following shift position left/right. That may be your issue here if you have different inside and outside margins.

Margins are identical. The strange thing is all content shifted to the left throughout including the Blurb gray safety zone. I reselected all pages and assigned "parent A" but nothing changed. Also reached out to blurb and they said Adobe issue. Very frustrating because I'm caught in the middle.  I might have to manually shift all page content back. Then do a test PDF to determine if on the grid and with nothing is cut off. Thanks for your comments
