mdb-datatable-2 small and hoverColor dont work

Expected behavior

Using small in Datatable should show smaller lines

Using hoverColor should change the hovercolor

Actual behavior

Using small in Datatable should show smaller lines but i cant see a different between setting small or not

Using hoverColor should change the hovercolor but this only works together with multiselectable. Without multiselectable the color is standard gray
