Wrong serial number was registered

I installed a Streaming Stick 4K about a week ago. When it works, it delivers excellent video and audio together. However, it has constant connection issues and I have to go through unplug/plug process daily and sometimes for a couple times in a day. I wanted to try to connect it to a different HDMI port on my TV and I needed an extension so I tried to order a free extender through Roku.com. After a couple futile attempts, I gave up on it. (BTW Roku needs to check on this order system since it’s not working.) While I was going through this order attempt, I found the serial number registered in my account was wrong. Since I didn’t type it in but the Roku pulled it out from the device in the middle of the setup process, I have no idea how and why the wrong serial number was registered. My question is if this wrong serial number could affect the performance of my Roku stick, and if it does, then how can I correct the registration info in my account.
