Scrivener format change after sync

It seems that the formate of files change after i’ve synced them.

If I open a file on my phone in iWriter, sync with dropbox and then open in Scrivener things like spacing between lines is changed.

Any ideas why this happens?

If you’re talking about general loss of rich text formatting, that is to be expected if you export to plain-text, edit in plain-text and then sync that text back into the software. It does its best to avoid areas of the files you haven’t edited, but within the paragraphs you do edit, understandably you’ll lose formatting.
