Hello,
Sorry for the delay in answering.
“As we can see, the default WooCommerce filters are not displayed at all on Arabic pages – https://prnt.sc/RVj_ETkdp6DB (en) and https://prnt.sc/ghU_YATBls0S (er)”
– There is a plugins compatibility issue – WPML Multilingual CMS,
WCFM – WooCommerce Multivendor Marketplace and
WooCommerce.
We have contacted the support of WPML and waiting for their reply.
You can contact support of plugins also.
Regards
