Maryland Form 500DM - how is "Other Changes" calculated (Part C line 8)

We have a handful of clients who have MD K-1s that report an addition or subtraction but who wind up with a change to the addition or subtraction on the 500DM. 

When we enter the addition or subtraction from the K-1 (on the Activity WKS) it goes to the 500DM  Part C line 9.  ProSeries is generating something on line 8 of Part C that results in an additional addition or subtraction.  I can’t figure out how ProSeries is calculating the number on line 8--there’s no cross reference.  I’ve read the form instructions and that isn’t helpful either--basically that it’s from MD decoupling from various federal laws.  Can anyone tell me how ProSeries is calculating this?
