I created custom map objects based on the Donuts:Alarms object, because I only wanted it to show 'Down' and 'Down Acknowledged'. So I customized the file and the include that comes with it.
Now, it seems that the number that is in the center of the circle is a combination of 'Down' and 'Down (acknowledged)' x2.
Here's the screenshot: https://i.imgur.com/8JO9wTU.png
27 Down and 20 Acknowledged make for a total of 47, not 67.
Another example: https://i.imgur.com/FAcEg1E.png
5 + 8 = 13
So every time, the Down (Acknowledged) is counted twice.
I know you probably don't support me creating custom objects like this, but can you at least tell me where this number comes from?
