I have modified my report transformation localisation for New Zealand, but there’s a niggly little detail that is bothering me. At the bottom of the GST report is a line (C15) that is either an amount owed or an amount refunded. The following code (in Liquid) might be doing something to hide the line that is not needed:
{% assign total = C15 | balance %}
{% if total < 0 %}{% else %}{% endif %}
but it doesn’t appear to do anything – it’s just an empty if-then-else structure.
The original report transformation hid the duplicate bottom line just fine, but when I edit the report transformation and then save it again, the bottom line looks like this:

Is there some secret non-ASCII content that got deleted somehow during editing?
