Non-sticky acknowledgements of soft non-OK states have been removed even when the host or service stayed in the same soft non-OK state. This was inconsistent with the way Nagios works and has been fixed.

Note: If you e.g. add a non-sticky acknowledgement for a soft-WARN state and the service goes to soft-CRIT, the acknowledgement will get removed. In other words: You acknowledge only the current state, not a general "non-OK" state, which is consistent with Nagios.
