Number of memebers inside my community site is wrong

Question

I have a community site collection which use to have three members, then i remove two members from the community site. but on the home page still the number of members under the "what happening" section is three instead of one as follow:-

and if i click on the members section , it will show one member, so why the members counter is still displaying three members ?

Answer 1

This is the default behaviour of the product. I don't know why Microsoft decided this because is odd. If you Leave the communnity still presents the same number.

I have already written to Microsoft so that they check it but it seems to be the desired behaviour because the community stores your historical data (badges, discussions, etc) and never will be removed

UPDATE

I want to show you a code to get the members of a community that are already joined.

SPWeb web = SPContext.Current.Web;

SPList Members = web.Lists.TryGetList("Community Members"));
try
{
    SPQuery query = new SPQuery();
    query.Query = "<Where><Eq><FieldRef Name="MemberStatusInt"/><Value Type="Integer">1</Value></Eq></Where>";
    SPListItemCollection colection = Members.GetItems(query);
    int membersJoined = colection.Count
}
catch (Exception)
{
}

The field MemberStatusId indicates if the member "belongs" or not to the community. If the value is 2 the member ever left the community. Actually, when you leave the community the field MemberStatusId is set to 2 and ReputationScore is set to -1

Create a WebPart with a label indicating the "real" members of the community using the code provided. Good Luck

Answer 2

The reason you get wrong number is the webpart is reading from the web property bag. So the option would create a new web part that is suggested by Alvmad above or updating the web property bag. The last option is maybe not be way. Since i'm not sure if this is even supported by Microsoft.
