I experimented around with it some more, and it seems to be somehow related to both the length of the text, as well as the number of spaces and partially to the variation of characters. But length is definitely the most important factor (just not length alone).
I'm uploading several examples of what I'm talking about. And the alignment issue isn't just in the comment field, it also seems to affect the "File Name" field depending on the length of the filename. If you download the image examples and compare them back to back, you can see that the "comment" and "filename" values are shifted to the right to varying degrees... which throws off the alignment with the other values.
look forward to hearing back from you

Btw, I just wanted to mention that depending on the length, sometimes the shift to the right is very small (but it is definitely there). If you actually download the images and flip between one and the other using whatever image browser you like, you can see that the text doesn't actually line up.
When it is a very minor shift, it's hardly noticeable and not a big deal, but I included those examples just so you can see how the shift to the right isn't a constant value, it seems to be determined by several other factors. The only reason I included those thumbnails was that I thought it might help you diagnose/rule-out possible causes of the problem being able to see how the shift varies.
