Sorry there was a typo… add_filters should be add_filter (not plural).

The below code has been tested and works:

add_filter( 'pta_sus_display_signup_name', 'pta_modify_signup_display_name', 10, 2 );

function pta_modify_signup_display_name( $display_name, $signup ) {
	return esc_html($signup->firstname).' '.esc_html($signup->lastname);
}
