After upgrading to version 6.3, I'm getting a stanza=_blocksignature error. After running the btool command, I'm still unable to find this stanza in the indexes.conf. Has anyone seen this issue before?

*Search peer Splunk has the following message: Found stanza=_blocksignature in indexes.conf. The block-signing feature is no longer available in Splunk. Please remove stanza=[_blocksignature] from the indexes.conf. For further details, please refer to the related topic in the latest version of 'Securing Splunk' manual on docs.splunk.com.*
