He intentado cambiar el tamaño de la letra en las etiquetas de columna y opciones de respuesta en una matriz pero nunca me ha sido posible, existe alguna forma para que no se vea la letra de estas así de montadas y separadas?

Build a matrix question in KoBoToolbox UI (do not forget to select Grid theme under Layout & Settings once you have completed formatting the matrix question).
