I am preparing a partnership return that has 25 partners.  In prior years, the K-1s would print in partner number order as would the related schedule of activities.  This year (2018 return) when printing the return, the K-1's are printing in random order (ie partner 1,15,2,16,3,17,4,21,5,18 etc.) and the schedule of activities are printing in an entirely different order.  It appear this is a Fed only issue as my state k-1s are printing correctly.  Any suggestions as to what is happening?
