results not rendering correctly

Hi, the plug-in was working fine over the past year. This morning the client just pointed out that the results are not rendering correctly. The results should (and was previously) render exactly the same as if clicking on one of the tags (below the search field). Not sure if this has anything to do with block/classic editor as it hasn’t been touched since it was installed. Any help you can provide is appreciated.
