Running any reports (default/custom) with any style does not retain the format when the files are downloaded from the RSA Identity Governance & Lifecycle User Interface Reports section. For example, the font color might not be retained or the font size might not be retained.

This issue is seen when using the Fill Report in Background button.

Below is an example of a Report in Classic Style that is not rendering the correct format.

A preview shows the correct format.

Run the report and click on Fill Report in Background. Then download the report in pdf format. Note the column headers are no longer blue as in the report preview.

Here is a another example using Fall Style. In this case note the column headers are no longer bolded.
