missing paragraph spacing when compiling to .mobi

Good morning,

I’ve been experimenting with compiling my MS to a .mobi file so I can see how it looks on my Kindle app (iPad). I notice that every few pages there is a missing space between paragraphs, where now the paragraphs are sitting directly on top of each other instead of a nice 2 space break. I go back to the paragraph in Scrivener and it looks completely normal, but the Kindle version seems to lose these spaces periodically. It seems to be random, and I can’t figure it out.

Any ideas what might be causing this?

Thanks very much for any information or insight you might be able to provide.
