Set the CNV1 for Conveyor Tracking

ftsp12

Hello, I'm a newbie in RobotStudio and I'm using RobotStudio 6.02. I want to make my conveyor tracking program, I've watched several tutorial video about conveyor tracking but still I have this problem: when I create new wobj (wobjCNV1) or whatever, I can't set moved by mechanism option even there are conveyor mechanism in my program. I try to create my conveyor system manually but in 6.02 there were no option conveyor (in modelling there is create conveyor option, I've used that but it can't be detected for create the wobj) Is there something wrong? How can I fix that? Please guide me, thank you for your attention RS masters.
