J-BusinessDirectory - CSV import augment vs replace

I have over 1,000 listings in my J-BusinessDirectory. Those listings did not have the website field populated. I created a csv file with the business name and website fields. I then imported it with the "Update existing business listings" option.

The result is that the listings now only have the data of the fields that I last imported. I don't understand why importing data for existing business listings would not just insert the data from the csv instead of erasing the data in fields that were not included in the csv.

Hi,

The actual mechanism considers that the data does not exist anymore and it clears it.
We will add another option to keep the existing data.
