UP message is ignored in SystemMonitorig

[Monitor02]

Hello together

We use the SystemMonitoring with Icinga. Sometimes we get the DOWN and UP message within 10 Minutes and OTRS catch both messages in one job.
In this case OTRS processed this massages (sometimes) in the wrong order. In this case we get the following message:

[Notice][Kernel::System::PostMaster::Filter::SystemMonitoring::_LogMessage] SystemMonitoring Mail: Mail Dropped, no matching ticket found, no open on this state - Host: Test123, State: UP, Service: Host
[Info][Kernel::System::PostMaster::Run] Ignored Email (From: ***, Message-ID: <***>) because the X-OTRS-Ignore is set (X-OTRS-Ignore: yes).

Is there a way to force the right order?

Thanks in advance
