go to file->preferences-> sheetmetal in the tab callout configuration you can check if this is the same as the customer defaults. and check also the Flat pattern display if the custom callout is set.
Some of the settings in the customer defaults are session settings and will work after restart. Some of the settings in the customer defaults can be over ruled in your part preferences. So these settings in de customer defaults you can see as a vault (database).
