Client Offline Session Max NOT OVERWRITES Offline Session Max

Dear all,

I setup the Offline Session Max on 3 days for a realm.
Then I wanted to extend this time with one Client and set the Client Offline Session Max on 30 days.

But in the refresh mechanism it looks like, that for the client in a Direct Access Grant Flow also for the Client a maximum of 3 days is been established.

Is that correct or a bug?

Thanks in advance.
