Title: Fix already used error using host and service label conditions
Component: Setup
Level: 1
Class: Bug fix
Version: 2.1.0i1
If you used label conditions in rules and the same key was used for host and
service labels, the error "Only one value per KEY can be used at a time.foo:bar
is already used." ocurred. From now on, each label type will be validated
seperatly.
