Running Clover coverage reporter inserts "com_atlassian_clover.TestNameSniffer$1@e628ccb" in to a test result and breaks build

I am trying to integrate Clover with a Java project at work. Clover has been added to the classpath, the plugin has been added to the POM and the license has been set up. When I run mvn clean clover:setup test clover:aggregate clover:clover Clover starts up correctly. However, tests that generate csv's fail because the CSV output is not what is expected. This is what gets generated for one of the tests:

<ID,NAME,[__CLR4_1_2_TEST_NAME_SNIFFER,"DESCRIPTION,Long","DESCRIPTION,Short",country
001,Fred,com_atlassian_clover.TestNameSniffer$1@e628ccb,Mr. Fred Flinstone,Fred Flinstone,US
002,Bob,com_atlassian_clover.TestNameSniffer$1@e628ccb,Mr. Bob the builder,Bob the builder,UK
003,Tintin,com_atlassian_clover.TestNameSniffer$1@e628ccb,Mr. Tin Tin,Tin Tin,FR
004,,com_atlassian_clover.TestNameSniffer$1@e628ccb,,Rob the Bob,
005,,com_atlassian_clover.TestNameSniffer$1@e628ccb],,Tom the Bob,
>

This is what is expected:

<ID,NAME,["DESCRIPTION,Long","DESCRIPTION,Short",country
001,Fred,Mr. Fred Flinstone,Fred Flinstone,US
002,Bob,Mr. Bob the builder,Bob the builder,UK
003,Tintin,Mr. Tin Tin,Tin Tin,FR
004,,,Rob the Bob,
005,],,Tom the Bob,

Why would Clover add a new column in to the CSV output, is it possible to stop it? I'm using maven 3.3, JDK 8 and Clover version 4.0.2.

I have tried looking for an answer but cannot seem to find anything similar to this issue. When I remove the failing tests Clover works fine.
