Manual product ordering not retained on import?

Hello,

I have all my product pages set up to display products on the front-end by the "Ordering" option in the product parameters "ordering field". i have it set up this way so that the products can be manually sorted to display in a specific order on the front-end, see attached screenshot to see how I have the settings set up. This works great and I am able to manually order products in the back-end and it gets reflected on the front-end as expected.

However, when I perform a product import all my manual ordering that was set up is not retained and all the products get reordered on the front-end and I must go in and manually re-order them after an import?

Am I missing something here? Why does my manual product ordering get wiped out when I try to update products with a product import file? Could you help me figure out how to retain my manual ordering configuration when updating products through the product import function?

I am also attaching a sample import file to inspect as well if that helps. From my own tests it appears as though the products always get re-ordered by product ID?

Thank you for your time!
