Or are you saying that the output in red (0.01211596 BTC) is part of your first transaction, that you didnt write that address in this tx and basically it showed up from nowhere?
Correct!
The output in red is basically the entire transaction of the previous unconfirmed payment I made. I did not include this payment with the current tx I was initiating.
The greed output was my actual payment. Including the fees it was suppose to be 0.00522031BTC but if you see the image, on the amount sent section it added up amount from previous tx too (total: 0.01711596 btc).
Basically I wanted to send the fund to a gambling site to bet. If I was successful to send the fund then I would lose the bet LOL (Lucky me)
Anyway, sorry about the off - topic. I am still not sure why it's happening,
1. Why the earlier tx included with the current one?
2. Is this the reason of the error(s) I experienced?
Sorry about the late response. I already forgot about this since I was watching the match that I was intended to bet.
Additional question:
What happen if I sign a tx but do not broadcast?
