Ok here @Perkin's file. Prestigio could open only one page of the original file, after conversion here is the link how the file looks like and how it is displayed on the Prestigio. I must say I was confused with the photo IMG-7025 because it dsiplayed styles ok then I noticed that user i asked to do this test while converting generated cover page from the first page of epub. Anyway, now we have all styles centered even those left aligned. I have huge problem because I don't own Prestigio myself to do all the test I want and getting frustrated with that.
Ok here is EPUB after conversion
Code:

I must add something I downloaded one book from the Feedbook page that was based on xml files, I opened it in Sigil added a cover and saved it in Sigil and it worked perfectly on Prestigio, all pages, all styles. But when you make a file in Sigil Prestigio doesn't recognise, convert it through calibre -Prestigio recognise (not styles though) and again want to make some changes save it in Sigil - Prestigio doesn't recognise again - sees only 2 or 3 pages.
