In the screen shot below I have put (1) & (2) at the front of each duplicate copy in order to distinguish the two of them.
In the front matter of the book they both show exactly the same copyright date, ISBN & and eBook ISBN.
But when you look at the support info the two resources were created a day a part and one of them has a different ISBN as the resource id
I did some research and found on Good Reads the Publisher released the book with this two different ISBN's 20 days apart with the one having the later date having 2 extra pages.
Since there are no page numbers in FL eBooks we can't determine whether FL are selling the 240 or 242 page book under the 2 different resources ID's.
And while the publisher may be responsible for there being the same resource under two different ISBN's with a count of 2 pages difference. FL has compounded the problem by not checking and questioning what they are converting and putting up for sale. They should now be conferring with the publisher which version to keep on selling and whether FL has the correct file for that version or not, they should remove the duplicate copy from sale. And they should search their records to see which customers have purchased both copies of the resource and providing them with credit to the value of the duplicated resource.
