Converted .epub to .mobi, getting double bullets?

Hi everyone,

I'm formatting an ebook in InDesign, and exported it as an .epub. The epub looks great on the Nook and iPad. When I converted the .epub to a .mobi using Calibre, the Kindle is showing all my lists with double bullets or double numbers (see image). Is this common? And, any idea how to fix it?

If I have to, I know I can try going into the code and deleting any extra characters. But I'm wondering if there's a quick setting in Calibre I should know about first.

Thanks for your help!
