new event incorrectly assigned to a irrelevant group according to activity stream

Hi

I created two events as below.
[*]
event1
This event was created via http://88.150.140.238/~a00000dr/dev/2016-05-20-00-11-35/all-events/steps/1
http://88.150.140.238/~a00000dr/dev/2016-05-20-00-11-35/all-events/item/154-event1
[*]
event2-group via group called "westminster"
The following group was created via http://88.150.140.238/~a00000dr/dev/2016-05-20-00-03-30/all-groups/item/10-westminster
http://88.150.140.238/~a00000dr/dev/2016-05-20-00-11-35/all-events/item/155-event2-group


However I can see that <blockquote>"admin created a new event event1 in Westminster."</blockquote> in my stream. ( see attached )
which I believe is a bug as I didn't create "event1" from a group called Westminster...?

Thanks for your support.
