I can't staking.
1. I made full resynch
2. I see masternode rewardd on end of synch
3. When staking is started, it make its own chain, so its impossible to staking.
I made this few times, for now I just losing staking reward. It's Definitely something wrong in new wallet.
Unlocking your wallet, let it sync, after that it will start staking after several minutes. Please check the icon status in the left corner in the bottom of the wallet (it should be green one to activate staking feature).
