When importing CSV into PrestaShop v22.214.171.124 through it’s Back Office (BO), the import is successful.
However, in phpMyAdmin section, I noticed the importation duplicated the products five times; each with a different id_lang. This seems overboard on how many products are consuming the php memory and should only be uploading the one language as per selection in BO.
In the BO upon importing your CSV, you can select the language from a drop down menu. The 5 languages that are offered as options within the drop down menu are consistent with the importation found in phpMyAdmin. It appears that the CSV importation, did so for all 5 languages and not the one selected one (English).
According to PrestaShop’s Bug Tracker the CSV imports all languages as a default behavior.: http://forge.prestashop.com/browse/PSCFV-4972
After some more research and troubleshooting, I decided to remove the languages instead of disabling them and it works!
