Error running GenericMonteCarlo mover within MultipleOutputWrapper mover

Hello Rosetta Users,

I have been trying to write and test some design protocols using rosetta_scripts. While testing a script, I have come across the following error:

protocols.rosetta_scripts.ParsedProtocol: added mover "net_charge_pep" with filter "true_filter"
protocols.rosetta_scripts.ParsedProtocol: added mover "set_up_foldtree" with filter "true_filter"

Looking at this, it seems that the GMC mover needs to be defined outside the MultipleOutputWrapper tag, as the erros says "mover not found in map". However, the documentation doesn't point towards any such requirement.  There are other warnings too. I am using rosetta version 2018.09. Maybe I have made a minor mistake or some changes have happened, not reflected in the documentation; i am not sure.  Please suggest a solution to this. The xml file is attached herein.
