Retry check doesn't work as expected

Icinga conf:

template Service "my_passive_service" {
    import "base_template"

    check_command = "passive"
    max_check_attempts = "5"
    check_interval = 90s
    retry_interval = 90s
    check_timeout = 10s
    command_endpoint =
apply Service "my_service" {
  import "my_passive_service"

  assign where regex("*xxx*",


Icinga web behavior seems a little bit strange, since switching from one to another state level can overlap as shown in figure:

It looks like a bug in icinga2. Why is that happend and how to fix it?
