My notes are uncontrollably duplicating themselves - both in the Notes file and in the original document

:
I don't often use notes, but was trying them out as I began my study of Exodus - and now I am seeing this. Am I doing something wrong?
Okay, I think I discovered what I did. I moved from my laptop to my desktop - but did not shut the laptop's version of LOGOS down. Can anybody verify that this was the cause of my multiplying Notes?
