Hi,
I don't see any error on your screenshot.
However, what I see is that the quantity amount (1) is so close to the total amount that it looks as if it's one number.
That's because of the name of the product which is really big and thus pushes the width of the column to the minimum for the quantity column.
That should have been the same in any version of HikaShop so far.
You could either reduce the length of the product name, or add a bit of CSS to force the width of the quantity column in the email itself.
