Why doesn't it display new colors in Woocommerce filter?

Question

WooCommerce

Hello. Here's the problem: the theme in the filter displayed the color attributes perfectly. I decided to add several new colors according to absolutely the same scenario, but in the filter they are now displayed simply as white dice (screen below). Although in the same product note, all new colors are displayed normally. And in the list of attributes, they are also reflected in their own color. The display is configured exactly as a color display, and not as a display of a picture that needs to be loaded (I know, some people add pictures with different colors).

Already broke his head - what could it be? I cleared the cache, the slugs are unique. I would be grateful for a tip!
