Here's the 0.14 screenshot, it shows 0 available balance

The Abandon transaction is grey out.

You will need to delete the mempool.dat file in the datadir and start Bitcoin Core with -walletbroadcast=0 then in order for Abandon Transaction to become available.
The Abandon transaction is grey out.

The 0.12.1 shows the 6.93 balance but does not have the any transaction record anymore, not even the first 5BTC one.

If you did zapwallettxes then it won't know of any of your unconfirmed spends and show only what is in the blockchain.

The first transaction is already in block 457837 though, just not confirming yet, so I am not sure if it will be forgotten.
There's finally 6 confirmations and the balance is reflected in my exchange wallet now. It then detect the -6.93 transaction and marked it as a conflict, and my remaining balance in my wallet still has 1.93 BTC.

That is the 5 BTC transaction that I sent before. It was shown in block 457837 but was locked with no confirmation for like 10 hours. I will make sure to check the on-going rate for fast confirmation next time I need to send BTC.
The 1DvNDLojJ9BAHfAaCCyxU65QZ6y4naup5j address cause me to panic as I don't know what it was before. Thanks for your help and clarification.
