Problem:
When a trade, transfer, (or other) has a description with commas “,” in it, those are not treated accordingly and hence the CSV export gets confused.
Solution:
The should be escaped, as far as i know using " " around it is the standard procedure.
Note:
I like the adequate long description field, as for some transactions I rely heavily on it understanding what i was doing / how i calculated some untracked $ altcoin values
