Bookify restrictions

I always design my cover after i have completed the book. Last night i started building my next book using Bookify (i wanted to get the 25% discount :) After uploading all the photos and making the page layout i moved to the cover. Unfortunately it turns out that Bookify is not supporting Cyrilic characters in the titles !?! Why ? Booksmart supports them.

I have wasted 3 hours on this, now i am building the book with Booksmart, will upload again but unfortunately wont be able to get the discount :(
