Hi,
It's hard to say anything without more information.
What is the difference between the products that were imported and the ones that weren't ?
Some have images and the others don't ?
They have prices and the others don't ?
They are published and the others aren't ?
...etc...
You should first check meticulously the products to see what's wrong.
But for only 100 products, I wouldn't bother trying to find the issue and just recreate the products in HikaShop. It shouldn't take that long and it will be a lot easier than trying to fix a complex problem with resets of the databases necessary to import again the products many times over during the tests, etc.
