Comments are duplicated after uploading a PDF to Share for Review
Periodically I experience an issue where I add several comments to a PDF, share that annotated file with others using the "Share" button, then a day later notice that all or some of my comments have been duplicated. See below from an incident that happened today:

In today's incident, when I opened the file, one version of each comment used my photo and my name in title case, and one version of each comment used a red and blue cartoon avatar and my name lowercase all one word. I deleted all the cartoon avatar comments. Then restarted Acrobat. When I opened the application again, a third of the deleted comments were still there, but this time it showed my photo instead of the cartoon avatar. I deleted all the comments by the lowercase, one-word version of my name. Then closed the file and opened it again. This time, the same comments had returned again, but showed a gray icon for my avatar.
WHAT IS GOING ON?!?!?! This same issue happened on two different files that I shared yesterday.
