I've got a shared Spreadsheet where people have commented and saved their comments, but when I goto see those comments their background has been filled black. This is the case for all the comments. I can go in and change the Font Color of the Comment so I can See it, but there are a ton of comments and I think it's a setting or formatting issue.
I've attached an example of the comments that I pasted into a new spreadsheet.
I wasn't sure if anyone else has run across this issue as well or knew the solution for it.
