BSM alarm severity is not being updated

If you have a BSM and child BSMs the BSM alarms of the top level BSM will not change the severity.

See attachment 1 and 2.

If the BSM "Ceph-Global-Status" switches to WARNING, the BSM "Ceph-IT-DEVVH" will turn to WARNING too.
If then BSM "Ceph-OSDs" brings MINOR, the BSM "Ceph-IT-DEVVH" will also turn to MINOR (which is correct!)

Now the part which seems to be not correct.
Have a look at picture 3. It presents the state of picture 2.
BSM alarm box and BSM donut shows 2 MINOR alarms.

But if you look at picture 4 there is the state of picture 1 where the top level BSM was at WARNING (alarm 44). It counted the MINOR change as you can see at the count value.
But the old severity which was WARNING stays.

I think, it should be MINOR now, shouldn't it?
