Hello,
Mohamed performed some tests using a similar CSV file.
He detected an issue in the Mass Action import system and after a deeper investigation we saw that because there was no "product_parent_id" in the CSV, some algorithms in the mass action system were skipped.
So we changed things in the system to load that information if it's not present and with that patch the CSV were correctly read.
Without the patch you need to add a column "product_parent_id" and specify the id of the parent (which is "0" when you are not using variants).
Afterwards, because you now have a rule to set a product price, it can generate a side effect.
I would more commend you to have a non obtrusive action like "display the result".
