hello,
I created an extrafield for csv file in J3.1.5 and K2 2.6.7
Everyhing fine when I create the item, i add the csv file name, and the content of the csv file is added to the item.
problem comes when I update anything on the item : content of csv extrafied disappear.

I looked in the database and the id of the field remain, but all values from csv disappear {"id":"5","value":""],[""],[""],[""],[""],[""],[""],[""],[""],[""],[""],[""],[""],[""],[""],[""],[""],[""],[""],[""}]

what can i do for my updates ? is this a bug ?
