5.9RC1, twentytwenty-two theme, jetpack subscription Block displays html code

i/m playing with twentytwenty-two theme. noticed when I select Jetpack Subscription Block, it displays fine in the backend editor but not on the page where it displays the following instead of the form:
[jetpack_subscription_form show_subscribers_total="false" button_on_newline="false" custom_font_size="16px" custom_border_radius="0" custom_border_weight="1" custom_padding="15" custom_spacing="10" submit_button_classes="" email_field_classes="" show_only_email_and_button="true"]
