Are you using the preview? If so - then don't use the preview, it's broken.
Do you only have 40? You can do it autonumbering instead, which would be faster to setup.
Only 40 this time (A test print - we need 3k)
Nope, not using the preview - clicking OK and seeing the ticket start at 2 then goto 3,4,5 and 6 on the edge of the document/artboard. The next page then starts at 7 which is not as expected ;-;
- This began only placing 3 on the page so i adjusted the 'bounding box size
