[Peter C. Petersen]

Describe the bug
In the admin interface in the list view. I am not able to export to xls. When I click the button I get below error:

You can see from the stacktrace this this error is coming from the xlwt package which has been deprecated since 2016.
I suggest export to xlsx if you can.

Closing because we cannot provide a fix for this issue.
