PowerEdge shows Error by lookup value 'Other' in channel 'Cooling Unit Status'

I have added a new Dell PowerEdge T430 iDRAC 8 to our monitoring system. We get the following seemingly spurious error (no Errors reported on iDRAC logs): Error by lookup value 'Other' in channel 'Cooling Unit Status'

Cooling unit status comes from oid 1.3.6.1.4.1.674.10892.5.4.200.10.1.44.1 and reports as "1". Most values in the sensor are "translated" by a so-called lookup named "prtg.standardlookups.dell.dellstatus", therefor the sensor reports "1" as "Other" which is defined as error state in the lookup: 

<?xml version="1.0" encoding="UTF-8"?>
<ValueLookup id="prtg.standardlookups.dell.dellstatus" desiredValue="3" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="PaeValueLookup.xsd">
<Lookups>
<SingleInt state="Error" value="1">
Other
</SingleInt>
<SingleInt state="Error" value="2">
Unknown
</SingleInt>
<SingleInt state="Ok" value="3">
Ok
</SingleInt>
<SingleInt state="Warning" value="4">
Non Critical
</SingleInt>
<SingleInt state="Error" value="5">
Critical
</SingleInt>
<SingleInt state="Error" value="6">
Non Recoverable
</SingleInt>
</Lookups>
</ValueLookup>

You can verify with our SNMP Tester what the oid reports (use option Custom OID in order to query the OID).

We cannot tell why the device reports this status, PRTG simply translates it using the lookup (which again is based on Dell's MIB definitions), therefor please contact Dell, a firmware update seems to fix the issue.
