Filters Not Showing

[alxure]

is there a way to add this product into correct filters in my collection?

i already have metafields products that are displayed as filters on search and discovery for, size, colour, product type, shape.

But I cant add all these sizes to appear into each size filter like - (600mm, 750mm, 900mm)

@alxure Hi, did you add these sizes as variants in products or they are showing from metafield or custom code?

and can you also share your store URL?
