On CEE 1.6.0p16, host in scheduled downtime still sends service notifications

I was hoping that by putting a host into a scheduled downtime that it would stop notifications while in that downtime. But in the case of our Kemp load balancer, checkmk continues to send out service notifications for the load balancer during its downtime.

Am I not understanding things correctly? Or is there somewhere I should look to fix the problem?

Replying to my own thread. Seems we changed the names on a service on the Kemp, and our rule to apply a label to that service was no longer being done. My bad.
