Why do duplicate collections appear when importing multiple items?

[orbita]

Hi,

I've been working on adding a large amount of products into my store. I've exported the full list from my products list, and added in the Collection column as described. I decided to test it on a small sample of products first.

The issue I'm having is when there is more than 1 item with the same collection, it's creating another collection just for that item. There are different items in each collection with the same name. I need all the items in one collection to be grouped together. I've tried creating the colleciton first but I get the same issue.

Now I've tried it again it's created the duplicate collections but showing 0 products strangely. 

Help would be very much appreciated!

Hi Ketan,

I can delete them, but when I try to redo it I get the same problem again.
