Hey Alan,
the text in the 2×1 tiles in tag-filtered views are sourced from the “Description” field of the respective tags, which you can alter in the “Portfolio -> Tags” admin section, by clicking on any of the existing tags on the right. WordPress automatically removes all html from such fields, so only plain text is possible here at the moment. If you’d like to remove the 2×1 tiles completely, please let me know, I will provide the instructions.
Sincerely,
Andrii / Satori Studio
