I have a Smart Object that contains a function which retrieves a list of SharePoint users, I used the SmartObject Service Tester to test this function and it is getting the complete list.

I have a K2 role that maps the destinations using this SmartObject Function, but unfortunately the K2 task or Worklist Item doesn't reach all the users.

Example:

The Users that are retrieved by the SmartObject Service Tester:

domainNameUser1, domainNameUser2, domainNameUser3, .... , domainNameUser15

When I check the worklist from the K2 management console, not all the users have the task only some of them.

I removed the SmartObject from the role and added 3 users manually so that the role only contains those three users, and the task reaches the three. 

Does K2 have a maximum number of users in a Role, or maximum number or users per task, if yes where is this configuration?
