Plugin no longer works properly since updatring to the latest version

Hi,

Since updating, I am having problems importing a CSV file. Almost half the products do not get imported and I see this error:

Product with same title already exist.

In the past, I was always able to import many products with the same name; they would import under different IDs. However, in the latest import, some products with the same names are being imported while other are not so there is no consistency with this problem.

Is there a fix for this?
