Unable to parse oid with output type BITS

Polling snmpv3 discovered item.

When polling a mib/oid whose type on the remote device is "BITS", Zabbix item goes unsupported with error: Received value [?] is not suitable for type....(note ive tried Char, txt, float and Decimal)

Here is an example of the mib and value as polled manually via snmpwalk from the proxy that runs the discovery.

.iso.org.dod.internet.private.enterprises.cisco.ciscoMgmt.ciscoVtpMIB.vtpMIBObjects.vlanInfo.vtpVlanTable.vtpVlanEntry.vtpVlanTypeExt.1.1 = BITS: 80 vtpmanageable(0)

Please see screenshots.
