Please see attached file, in particular, Bud Men Roster Query.  Starting from top, everything is fine until the expansion of the "ADP with Drafted."  I have no idea why, but it's changing the "Distinct Pos" of Carlos Santana and Paul DeJong after the expansion.  Santana goes from C/IF1 to C/IF2 and DeJong goes from C/IF2 to C/IF1.  What's causing them to change?  The same occurs with SP Zach Wheeler and SP James Paxton.  Wheeler goes from SP2 to SP3 and Paxton goes from SP3 to SP2.  I've redone this several times, multiple hours.  I cannot figure out what's causing this.  The merged numbers match up perfectly.  Any suggestions?  It's driving me nuts.
