Zoho Desk - Macro action is not being applied on all selected tickets

Hello, 

I have a macro button that executing function to update the selected tickets
  1. mp = Map();
  2. mp.put("cf",{"cf_whats_app_message_triggers":"6 month retention"});
  3. update = zoho.desk.update(org_id, "tickets", ticket_id, mp);
this is the function, it's very simple.

However when I select for example 50 tickets only few of them being updated.
I executed macro twice first time only 5 updated second time only 15.
