Please excuse me but I am new to K2.
I have 2 categories of items, News and Messages
On the Messages category I want to add two extra fields (Startdate and Enddate).
I created and Extra Field Group (Dates)
I then try and add the first field.
The first problem I find is that K2 will not allow me to add the filed to the existing group (Dates), but i get message 'please elect a group or create a new one'.
If I do this and then try and add a second field to the group I have created, I get the same problem.
So I can't add more than field to a Extra Field Group.
What am I doing wrong???

K2 Category (Messages) Associated extra fields group (Dates)

I have found out it is a known problem
