Known issue on MERG Forum, first appeared Feb 2017, current workaround to use internal consist.

Advanced consisting apparently works fine with the MERG DCC base station + handhelds, the CV19 thing is supported by MERG CBUS Opscode PCON ( 0x45 ) add to advanced consist + KCON ( 0x46 ) for removing from the consist.
See section 9.2 of MERG CBUS developers manual.

If a decent amount of work needs doing to sort this, perhaps a temp. fix to force internal / hide MERG in the options until resolved would help new users?

Many thanks to @silverailscolo the Consist option can't be selected, as requested for user experience temp fix.
Low priority to implement MERG advanced consisting imho, not requested by any users so far AFAIK.
