Additional context
I suspect that there is something in the file names that might be filtered out, or alternatively a off by one error.

It's because of the statistics generation in the background on the server. Your files don't seem to have come with a size throwing off the calculation. I'll check on that, and move the toFixed off the page so it's not an issue at the very least.
