Filter does not work

Hello Manan

Read this please: https://www.woocommerce-filter.com/filtering-by-product-attribute-doesn-work/

but my terms are only once single name like brands , size. that’s it but still it doesn’t work.

SO can you help me more on this?

but my terms are only once single name – use attributes as taxonomies – the plugin doesn work with text data https://clip2net.com/s/3vrF8U0
