The RC Manabar is for posting, commenting, claiming rewards and voting for witnesses.
The Voting Manabar is for voting.
They forgave all the debt for the RC Manabar so everyone started at 100% (yours has depleted because you've been busily posting and commenting since the debt forgiveness).
The problem is, the voting manabar started at 0% yesterday and is slowly rising - you are just over 20% because it's been about 30 hours since the hardfork and you've probably done just a few votes.
If they'd reset everyone's voting manabar to 100% at the hardfork, they'd have had fewer complaints.
