This issue can occur if the report style that the archived report is based on is no longer present on the system. This should not occur normally but may occur if the report is migrated from a different system that does not contain the same custom styles.
This problem has been reported as engineering ticket ACM-63770 to be fixed in a future release.
Perform the following steps to resolve this issue:
Save the report definition specifically with a new style such as the "Default Style".
Select the problem report.
On the bottom of the Edit page press the "Style" button.
Select the "Default" style from the list of styles and press OK.
Press OK again to save the report.
New reports generated from this report will now format and display correctly.
