Custom SNMP Trap Message

I opened a case with F5 and found my answer. The OID I picked was designed for 4.x BIG-IP devices. If I use something in the form of 1.3.6.1.4.1.3375.2.4.0.XXX, all SNMP traps started showing the full message from the logs:

alert BIGIP_CUSTOM_TEST "testing notification" {    
 snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.200"    
 }

My mistake was using the wrong document to set up the traps. Here is the document I initially used:

Here is the one I should have used:
