I was setting up a masternode and I sent 20 SUB1X to the masternode address. It didn't seem like it worked, so I sent another 20 SUB1X to the same address. Well, it turns out the first payment did work, and shows up in my transactions as "Payment to yourself" with the amount listed as just the transaction fees.  The second payment (the mistake payment) of 20 SUB1X to the same address, a few minutes after the first, shows up as "Coin Mixing Make Collateral Inputs."

So by sending more than the required SUB1X to my masternode address did I enter my coins in a mixer? Is there anything I need to change now that I've done that, or should things be okay? Thanks for any info.
