Oh, you mean that you have set the Not Applicable item to other specify. I thought you were referring to a list item of your select / ranking question. I hadn't thought about supporting other specify N/A before now.
I've added this to the list of changes to consider the next time I update the Community Question Library. But I can offer a quick hack that ought to work for you in the meantime. Locate this part of the Not Applicable question's footer:
$(qdiv).find('input[type="text"], input[type="tel"], textarea, select').val('').prop('disabled', true);
And replace it with this:
$(qdiv).find('input[type="text"]:not([id^=[% QuestionName() %]_]), input[type="tel"], textarea, select').val('').prop('disabled', true);
