Mouse issues

I just bought the new Dark Core RGB Pro SE mouse a couple weeks back and I love it overall. However, this has been happening ever since I got it. It seems to add another (1) almost every time I load up my PC or power on my mouse. I'm not sure if it's really having a negative impact on anything, but it's a little annoying and definitely seems like an error. Is there a fix for this? Also, when I start up Minecraft, my mouse lighting freezes, and then shuts off. The light just below the scroll wheel is flashing yellow periodically, but I don't know what it means. All other functionality on the mouse works and it's on the right profile because my rebinds work, but I have to turn it off and back on again in order to get the lighting to work. I use my mouse in wireless mode too. Any help for either of these issues would be super appreciated! Cheers!
