Application Loader not showing option to import inAppPurchase

I have a weird case, I have application loader 3.7 and I want to use to upload a mass of in-app Purchase items to iTunes. But to my astonishment the the button for import and the one for in-app purchase no longer shows on the application loader as shown in the screenshot.

I tried loading previous version 3.1, but same problem occurred.

What could be wrong with the program, and is there any alternative for submitting the items?

After contacting the Apple team they have assured that there is no current way to upload a bulk of in-app purchase on iTunes but instead they have suggested that we create a set of items based on their price.

For example, we sell eBooks so we have created items like eBook1 that stands for all books that cost 1$ and eBook2 for all books that cost 2$...
