Package and version @medusajs/search-postgres 2.21.2 (latest), Medusa 2.21.2, PostgreSQL 17, keyword search (no vector). What happens A /store/search query with search_options: { typo_tolerance: true, min_score: 0.5, facets: [...] } returns hits and a count that respect min_score, but facet counts that don't. In typo mode the match predicate is ... OR word_similarity(...) > 0.3, so the facets count every product above 0.3, while the hits stop at 0.5. On a catalog of about 10,000 products, the query lavendl (typo for "lavendel") returns 24 hits, all plants, but its option facets include values such as "Verpakking: Bigbag 0,5 m³" that only bagged soil products have. Filtering on one of those values returns 0 hits. For buxsu, 79 of 92 facet counts didn't match the hits a filter on that value returned. Expected The facets are scoped like the hits. The doc comment on buildFacetScope says so: "the filters plus the same match predicate as the hits, so facet counts describe the result set." C

Package.json file { "dependencies": { "@medusajs/dashboard": "2.21.2" } } Node.js version v24.14.0 Database and its version Not applicable: the bug is in admin UI text and happens with any database Operating system name and version Windows 11 Home (10.0.26200) Browser name Chrome What happended? In the admin dashboard, the sort menu for date columns (Created / Updated) shows "Newest first" and "Oldest first", but each option sorts the opposite way. The "Newest first" option sets desc: false (data-table-sorting-menu.tsx in @medusajs/ui). The dashboard sends that as ?order=created_at (transformSortingState in data-table.tsx), and the backend treats an order without - as ASC (get-query-config.ts), which means oldest first. The cause is in en.json: filters.sorting.dateAsc is "Newest first" and filters.sorting.dateDesc is "Oldest first". 33 other locale files copy the same reversed meaning. ar.json is already correct because it uses neutral "ascending/descending" wording. Affected:
