Koh Young Fiducial error multi-up panels | 10 June, 2019

I am able to create a single board program using gerber and centroid, and teaching footprints. I can then assign 2 global fids(a third never seems to display in Ceditor), and export my pad file. I then open it in ceditor and export the job file. Load the job file and it runs great. My problem is with multiple images. I follow the same steps, except I only teach footprints on the root image. I then create the other images(blocks) from the root image under the board array tab in the epm software. If i assign 2 global(panel)fids, Ceditor gives me an error"can not find fiducial"when i save the job file. Using global fids, I can literally just delete the other blocks in EPM and it will work. If i assign 2 local(image) fids, the fids are mirrored in their posistion when I open the Pad file in Ceditor. Also, I have noticed the PCB info screen that prompts when you first open Ceditor, Will say the correct array number at the bottom, But will have 0 listed for number of fids. What am I missing here? Why can I not get multiple images to work? Any ideas? Thanks

From what I understand, in the PCB Info window that first pops up when you open CEditor, the number of fids is multiplied by the number of arrays. So if you have a 4-up panel and you enter No. of Arrays = 4 and No. of fids = 2, the machine will look for 2 fids on each of the 4 boards. I'm not sure what happens when you enter 0 for fids. When I do arrays, I'll export from epm without fids, enter 1 array and 3 fids, then apply my 3 fids in CEditor. I suppose the 3 fids are like pseudo-global fids.
