Wrong background color in AML when a reactivated alarm is acknowledged

Hello,

I have noticed that wrong background color is appearing in AML when a reactivated alarm is acknowledged. Please see attached document where I cumulated relevant screen shots.

Also note that "use reactivated time" setting is selected in the Project settings.

Is this a kind of malfunction of the software or am I doing something wrong? 

Thanks,
Emir
