Hi Jacob,
we had to activate "Display Catalog Name presented by vendors in Search Results" in the customizing of "SAP SRM User Interface Add-on" under "Enable Enhanced Search".
We were not able to find out the reason why the checkbox has to be checked...in my opinion it is an error that this checkbox has such an effect to the view-functionality or it is not documented enough. We found out that this checkbox is necessary after hours of debugging the standard code for displaying search results...
Please let me know if this solves your problem too.
Kind regards,
Hauke
