Problem importing csv file

Hello!
I have some problems importing the reviews with your plugin.
The problem is that the system is importing only the first pictures of every review. Some reviews have only one pictures, but a lot of them have more than one.
I created two fields in the csv field trying to fix the problem, but the point is:
– If I use the field with the imagen´s url between quotation marks, then imports all the picteres except the firts one
– If I use the field without quotation marks, then imports only the first picture.
Eventually I used the field without quotation marks in order to have at least one picture for each review, but I need to fix this problem get all the pictures imported.
I can send you the csv file in order you can analyse what the problem is.
In the csv you can find both fields used to export images
