The change sample rate/change resolution function bug when used in the Batch Processor has been fixed in version DCArt10.6x. If you have DCArt10.5x, uninstall it and install this version (it's free for DCArt10.5x owners):

Your DCArt10.5x registration will be automatically applied to version DCArt10.6x.
