Setup data merge with bleed catalogus
Its been quite a while ive worked with data merge. Now im trying to test if data merge is better than using linked xcel files in tables and how they update after changes. But its tedious work setting all pages and linking it. I've made a master with four tables on then plus headers, these are separate tables using the same file. Ive added cell range so i can keep the header styling as well as the body.
What i like about data merge is that its super fast creating pages. But i run into issues when my design has bleed. Ive tried setting up a page with the bleed already in there but i then got a problem when i scale the page down again to A4.
This is my setup with linked excel sheets, where separated the header for the product name.

This is my setup trying to do data merge, page size setup with bleed added so i can use bleed in my design (A4 + 3mm)

The trick im trying to pull of is that i make the pages with 3mm extra so A4 + 3mm = 213. Then later i resize the page back to A4 which makes the back stay and put the design sort of in the correct place. Problem is that i see a minor offset

The spin of the book gets 15mm margin and outer sides are 12.5mm. Im wondering why i see the tables on the right page at a different location
