The page I linked to below should open with the filters expanded rather than collapsed. This is set via a setting in The Events Calendar. It works if I use a default theme, such as Twenty Twenty-Five, but not with Parabola as the theme. I have been working with The Events Calendar developers to trouble-shoot this issue but they are saying that it is an issue with Parabola and to contact you.
