Why can't I import my modified CSV back into my database?

I Exported my dataset to CSV format, bulk edited some data, and cannot import it after that, my db is almost empty now.


I had a tiny data set on my Shopify webshop with ca. 40 items.

I exported it into CSV format to bulk correct some typo’s, and html descriptions. After the corrections, I imported it back, but my database contained duplicated entries (with the new corrected versions)…and… as I wanted to fix that I deleted all of my entries, made a sample product as a starting point of a new db but I cannot import my CSV file anymore. I see a success message but no entries after that (except the sample product’s I created manually).

Did I misformat it? The format I used is utf-8, en-US, comma separated.
