Hello,
the listing will show the default header of the default category or the first category selected.
When I just checked one of the listings, it does look like there is only the one category assigned.
We would be happy to take a look at your settings to see if we can find the problem.
Please be sure to have completed all the steps for configuration, and do check to see that your plugins are all up to date.
To allow us to examine the site, please create a private reply and include all the information listed below so we can make a complete diagnosis.
