I have four copies of my mouse on one computer and three more copies of the same mouse on another, with seemingly no way to remove them. I already tried what worked for a few other people after scouring the depths of online fora. It seems this is just a bug that hasn't been fixed yet. It doesn't impede functionality per se, but it is incredibly annoying, and is affecting my experience of the product. Also, all seven copies appeared instantaneously when my other computer decided to recognize the several times I tried connecting this mouse, until which point it was showing none of them -- connecting to my computer itself by bluetooth was working fine, but logi options+ seems to be lagging in recognizing them, and cannot "forget" devices no matter what I try.
