I asked earlier but didn't get an answer.

I tried to create a alias but the Qt complained error:
Error creating new alias: "Error, transaction creation failed "

Now I tried second time but still doesn't work. I've got two 1.002 transactions that are stuck. How can I cancel or remove them?

Did I do something wrong? I first made a syscoin address for receiving payments. Then I pressed the "new alias button" and I did put the alias there.

Have I understood wrong what aliases are (shortcuts for payment addresses?). There is no info of them on the OP or website.

Edit: these fees seem to be collecting confirmations forever. One has already 54 confirmations. Do they ever end? The sent to: is blank.
