Overdrive issues in Pandigital Novel device

Here is an Overdrive issue with Pandigital Novel I came across while doing a BAL and I think it may be an issue for some other non-mainstream e-readers.

The problem is that even though one can easily download both Overdrive app and e-books on Pandigital, when opening such a book in Overdrive one can see only a part of the text: about 2/3 to be exact. Text size adjustment does not do the trick, nor do any changes in Settings.

The only way out that I found was sideloading a book on the device and then opening it with some app other than Overdrive (such as B&A app on Pandigital, for example) or getting a Kindle app and downloading a Kindle format book from our collection.
