Small amounts of physical damage can fail to convert when you have over 100% conversion, depending on the actual distribution. This is due to rounding, and adjusting conversion above to 100% to provide 100% conversion (in other words, not turning conversion above 100% into extra damage).

Your distribution is:
49% converted to cold -> 49/104 = 47.12% rounded to 47%
15% converted to lightning -> 15/104 = 14.42% rounded to 14%
40% converted to fire -> 40/104 = 38.46% rounded to 38%

With the total conversion ending up being 99%, a little physical damage fails to convert.
