im working on a ticket vending counters project, in that I have multiple sources in which the male and female will generate from their respective sources, they need to interact with their respective staffs at counters as it is in my process flow, but while interacting, only one person needs to acquire the staff, so to gain that I've used zoning in my process flow but at some point of time more than one person was acquiring the staff when I run both male and female sources at a time, zoning was fine if I run only female or male sources individually, but while operating total male and female sources the zoning was not happening properly at the counters. (I've created individual process flows for staff acquire and animation for both male and female for the counters i.e., I've two different process flows with same attributes, i.e, for male and female)
