Thanks so much for collecting the job.
After nearly pulling all my hair out, I at least found the source of the issue, but it just creates another...
When imposing an FP project where a DSN file is my data source, the imposition file creates full stacks of 100, regardless of whether or not there is enough data to fill the stack. When the FP file is linked to a CSV (simply exporting the same table that is being read in the DSN - i.e. same data), the stacking works properly...
So, now that I know what's causing it, my obvious next question is why this would be a problem and if anyone knows of a workaround?
