In the paragraph menu flyout menu, choose justification. Most likely the freehand values imported into here are different. Illustrator justification does not work perfectly when you use values different than the standard:
Word: 80%, 100%, 133%
Letter: 0%, 0%, 0%
Glyph: 100%, 100%, 100%
Negative values especially drive Illustrator justifcation out of whack.
