Dot ribbon Kadence Blocks appears fully black after update Twenty Twenty-One

Dear reader,

I am using the Advancend Gallery block of Kadence Blocks with a Carousel. After updating to the latest version of the theme Twenty Twenty-One, the bar with Dot style appears fully black (instead of white before). I have already contacted the Kadence WP Support and they explained that the bug is coming from the Twenty Twenty-One theme. They suggested to contact the theme’s developer.

In the meantime, they provided me the CSS code below:
.site .button:not(:hover):not(:active):not(.has-background), button:not(:hover):not(:active):not(.has-background), input[type=submit]:not(:hover):not(:active):not(.has-background), input[type=reset]:not(:hover):not(:active):not(.has-background), .wp-block-search .wp-block-search__button:not(:hover):not(:active):not(.has-background), .wp-block-button .wp-block-button__link:not(:hover):not(:active):not(.has-background), .wp-block-file a.wp-block-file__button:not(:hover):not(:active):not(.has-background) {
background-color: #FFF !important;
}

Is it possible to repair the above mentioned bug, so that the additional CSS is not needed anymore? Thank you in advance for your support.
