Virtuemart 3.0.9
Joomla 3.4.3.
I installed correctly plg_csviext_param_csvi_6.0rc1 and plg_csviaddon_customfilters_csvi_6.0rc1 and I've published it.
I've also tried to Update Field in Avaible Fields (Maintenance) before export/import.
I've also correctly bought and installed "Virtuemart 2 Product Filter by Custom Fields" for Joomla 3.
I created the Custom Field correctly using this guide.
If I try to import Virtuemart product all works correctly using standard fields (product_name, product_sku etc...), but when I try to import using "Custom Field" Fields ("custom_title";"custom_value";"custom_param"

An error has occured during the import. Below the information received from the server.
Status error: 200
Status message: OK
Notice: Undefined index: clearCustomValues in D:\xampp\htdocs\mysite\administrator\components\com_csvi\rantai\plugin\dispatcher.php on line 65
Warning: Invalid argument supplied for foreach() in D:\xampp\htdocs\mysite\administrator\components\com_csvi\rantai\plugin\dispatcher.php on line 65

While if I try to import without ("custom_title";"custom_value";"custom_param"

There's two file attached: import_error.csv that causes error and import_ok.csv that works ok.
How can i solve this error and how can I import vm product custom fields correctly? Thanks
