SNMP OID being added as MBean

I am trying to use Applications Manager to pull some performance data out of our F5 load balancer, but when I try to add the OID .1.3.6.1.4.1.3375.2.2.5.4.3.1.11.5.76.79.71.73.78.1.4.10.100.3.13.8080, Applications Manager registers it as an MBean and is then not able to pull data. (You can see the attached screen shot for more detail.)

- Testing the above OID with net-snmp shows that it is a valid OID and returns data.
- The appropriate MIB has been loaded into Applications Manager via the Add MIB form.
- Other OIDs like sysSystemUptime are added correctly by Applications Manager and data is retrieved from them.

Can you give an insight as to why Applications Manager is treating this SNMP OID as an MBean?

Thank you!
