it doesn't let me see all of my books that I have downloaded so far – Dolphin EasyReader Review

I have a lot of books on EasyReader, and when I went to download a few more yesterday, I closed out the app, and then re-opened it again, but it only says I have 100 books out of the 1000 or so. but then i check my i phone storage usage for the ap, it says they are still there, is there a limit on how many books you can have on easy reader?
