Curvature on rectangles revert to zero

I've had a recurring problem that two rectangles I've created - one token and one map - stop being curvey after I close and open the campaign. I've set them for 24 and 50 curves to simulate a ship and a submarine. They both revert back to 0 curvature when I open the campaign again.

Attached as a PDF and in text at the end of this message. Let me know if you cannot read them. The campaign name is "ICONS - Stark City Adventures" and the page is "Scene One - The Docks."

I was wrong. The curvature doesn't revert to zero, but instead changes to 6 and 12, which is even weirder I think because those are values the objects never had--they at least started out as zero.
