OK, Filter by price is capable of filter correctly as in your screenshot but only sometimes. In CUIDADO FACIAL menu, price range loads and filter ok and also in sub menu CONTORNO DE OJOS.
But it has two different issues:
1- in sub menu CUIDADO FACIAL > ROSTRO and all sub menus inside (serum, crema… mascarilla) filter price range loads wrong. For example https://www.ia-incosmetics.com/filter-by-price-rostro/ And same thing happends with: CUIDADO FACIAL > COSMETICA NATURAL CERTIFICADA, CUIDADO CORPORAL, HOMBRE and HOMBRE > CUIDADO DE LA BARBA
2- Every time I select a price range with “no products found” result the filter disappear like in this screenshot https://www.ia-incosmetics.com/filter-by-price-hombre-disappeared2/
