Notification on recovery without a problem notification beforehand

Hi everyone!

I try to send a recovery notification when a host recovers from a problem without sending a problem beforehand.
As far as I understand this should work following the documentation.

Only users who have been notified of a problem before (`Warning`, `Critical`, `Unknown` states for services, `Down` for hosts) will receive `Recovery` notifications.

Icinga 2 v2.10 allows you to configure `Acknowledgement` and/or `Recovery` without a `Problem` notification. These notifications will be sent without any problem notifications beforehand, and can be used for e.g. ticket systems.

This works fine but also reports problems:

template Notification "host-recovery-notification" {
  states = [ Up, Down ]
  types = [ Problem, Recovery ]

  period = "24x7"
  interval = 0

This is what I need but doesn`t work

template Notification "host-recovery-notification" {
  states = [ Up, Down ]
  types = [ Recovery ]

  period = "24x7"
  interval = 0

Is there a problem with the version v2.10 vs r2.13 or do I misconceive something here?
Thank you for your help
