ePub to Kindle... margins messed up?

[Zaimejs]

I am new here, and I did a search for this topic, but I can't find anything.

I created a document and converted it to ePub using Pages on my Mac. When I convert this for my Kindle, words are divided wherever so they get split as one word goes to the next line. This makes reading impossible.

I tried several different settings on Caliber to fix this problem, but I just can't get it to work.

Am I missing something obvious?

I just don't know what else to try. What is the easiest/best way to go from a document to a Kindle file to keep it readable?
