I recently installed two purchased components: Flipbook and Animated Image. They were purchased from the official website, but they still don't work properly, displaying error messages. In the page optimization section, I see error alerts, specifically about errors in these two added elements on the page. In both cases, the message is: "There is no alternative text for this object." I go into the add-on settings, but I can't change anything there because there's no option to add such alternative text. What should I do?
