I have three custom styles using an en dash as a bullet. These styles change themselves unbidden. Sometimes the en dash disappears. More often, the setting in the Paragraph command changes from .25 indent to .5, and sometimes the tabs change from .5 to .75 (and the other two styles may change as well).

Is there a way to corrrect this? Is it a sign of corruption? The style is based on Normal. Should I change it to No Style? Any suggestions. I don't want to deliver unstable documents to ur customer.
