PDFs - Kindle question

[rmp090946]

I always transfer the PDF files (manuals) for games to my Kindles: 1) 8" Fire; 2) Paper White for reading.

I've transferred this game's PDFs; but, have experienced the following:

1. All the "Strategy" PDFs are fine and readable on both Kindles & my laptop.

2. However, the "Main Manual" and the "Essential Guide" (after transfer) are highly distorted & not very readable at all. But, these same two (2) PDFs are clear & readable on my laptop.

Anyone have similar issue; or, a suggestion?

Thanks for any input.
