About line_item_x column in csv file

WordPress version – 5.2.2
Order / Coupon / Subscription Export Import Plugin for WooCommerce (BASIC) version – 14.9
line_item_1 column csv value –
name:Men’s Cotton T-Shirt|sku:B11V2|quantity:1|total:11.88|refunded:0.00|meta:color=Red|tax:0.00
(I downloaded and used the csv sample from here.)

Hello, I found that the values contained in the mentioned csv column were mapped to the incorrect fields in WooCommerce > Orders > (Click on any 1 of the orders) > Item section. Inside item section in which there is a ‘Refund’ button under it, I discovered some problems.

Problem 1
==========
‘Cost’ and ‘Total’ of item section both showed $0.00.

Problem 2
==========
‘Qty’ of item section took ‘11.88’ (the value in ‘total’ of line_item_1 csv column) and showed as ’11’ in in this section instead of using the value of ‘quantity’ of csv column, which is 1.

Problem 3
==========
The other details of line_item_1 column csv, for example ‘meta:color=Red’ did not show in the item section also. Actually where do those values will be shown?

Could you please clarify or provide assist in these problems I found so far? Actually I also have a question. Am I allowed to name the parameter of line_item_1 to other name? For example, change ‘name’ of csv column to ‘name_of_cloth’, ‘quantity’ to ‘quantity_purchased’?

Thanks very much for your assist.
