You have to write all features this way (without quotes but within semicolons): ";Case Size:1,Brand:Frontier Bulk,...,UOMPEREA:400" In this example ... means all your features between features Brand and UOMPEREA In Import CSV for column Features(Name:Value:Position:Customized) choose collumn above for import. Or You can add features names to each value ";Case Size:1;Brand:Frontier Bulk;...,UOMPEREA:400;" for each row and do import CSV as many times as you have features. In Import CSV for column Features(Name:Value:Position:Customized) choose each collumn above for import at a time.

Customized (...:1) means that value will be stored to the Alt values field (right one) (Catalog -> Products -> Features -> Alt) but not to Existing Values (added from Catalog -> Features -> Values) and will not be shown in Filters. Without "Customized" features and values will be added to "Catalog -> Features" and "Catalog -> Features -> Values" and to "Catalog -> Products -> Features -> Value" (left one) and can be used in filters. I have russian language interface so do not know right fields names from english interface.
