Before your wallet is synchronized with the network, this output is meaningless.
in console get_info
"blockchain_average_delegate_participation": "0.02 %",
You need to finish synchronizing to read "blockchain_average_delegate_participation" output.
If you're synched and get this reading, you are on a fork and should resynch.
"get_info" console command should tell you if your wallet is synchronized.
You may try "blockchain_is_synched" command.
