Cannot create group: group with the same name "XXXXXX" already exists.

Steps to reproduce:

1. Why when specifying a macro in a prototype group, it cannot add a host to the group I need?

{ "data":

[ { "{#HOST}": "ng-1.alpha.marathon.mesos.sportmaster.ru",

"{#GROUP}": "ESM_alpha" },

{ "{#HOST}": "ng-2.alpha.marathon.mesos.sportmaster.ru",

"{#GROUP}": "ESM_alpha" },

]}
