Different color on alarm journal table for clear, acknowledged alarm

Hi,
I don't know if it's "normal" but I have different color for clear,acknowledged alarms depends on the action done on the alarm:

  • if the alarm rise, the alarm drop and then I acknowledge the alarm, the alarm take the style of the cleared alarm:

  • if the alarm rise, I acknowledge the alarm and the alarm drop, the alarm take the style of the acked alarm:

Does anyone get some answer about that ?
Regards,
Valentin.
