snmptrap version2 issue

Hello, nowadays I'm suffering snmp trap v2 problem regarding opmanager. I'm using citrix netscaler mpx10500 as a load-balancer, and want to get snmp trap message from it. When I trying to use snmp version 1, it's ok. But When I chaged snmp version from 1 to 2, opmanager couldn't recognize it.

and finally I found some difference with verison 1 and 2. when I execute mib browser through web page,

I can see traps (attachment v1.png), but version 2 couldn't (attachment v2.png)

When execute mib browser in server (not web page), I can see traps even version is v2. (attachment mibbr.png) I'm attaching version 1 and 2 mib files also. Plz help me to solve this problem.
