......However, my experience with this problem is that it can be caused by having a comment wrapped around an image within the original Word document, which is not yet supported by the TagEditor filter.
I would recommend re-attaching the comment to some text instead and then retranslate the file using the Translate to Fuzzy option.

Thanks Gareth. This worked for me as well. However, I had to delete all the comments, not just the one wrapped around an image.
