Setting, options, click Display coin control feature. This allows you to reblock your coins.

Settings, unlock wallet (does it for staking only). Check the bottom right of the wallet for the green arrow appearing showing your staking weight.

Wallet must be running to stake and I personally keep my blocks from 6k - 20+k. Coin control is left on automatic whilst staking.

Pre-empting the next question :

Re-blocking your coins

 - set your passphrase to something short otherwise lock the wallet.
 - Copy your wallet address to the clipboard (receive coins, highlight the wallet address and Copy Address).
 - Send coins, tick custom change address and paste your address into the box provided.
 - Click inputs.., expand the blocks and mark the one(s) you wish to reblock. OK, paste your address into the pay to box and specify the
   amount. Send, blah, blah and wait 10+ seconds to process then repeat this part.
 - Reset your passphrase back and unlock the wallet.

Reducing the block size, keep halving the amount. If it's 50k then mark it and send 25k, two block of 25k will get produced. Creating
larger blocks, for example, mark 50k worth of smaller blocks and then send 25k. Again, two 25k blocks should appear.

If you seem to have lost coins check they have not been put into another address in the wallet. Send coins, Inputs..., expand blocks
and click address, if two appear, mark the new one and send the coins back to your prime address.

If still not adding up, Help, Debug window, checkwallet, if it does not pass, repairwallet.

Coins need to be in your wallet for 6 hours before they will mature for staking.

NOMP is incompatible with Cryptotarget because of decimal numbers.

Your pool never confirmed the blocks and never pay to the miners.

Check your code.

Looks like you will never be exchange

When will exchange?

We just disabled the Dogecoin Cash crowdsale at our site. The team's true intentions seem pretty clear from our point of view after we received multiple e-mails asking to lower the crowdsale price.
