This is likely a crawl lag + URL preference signal issue combined. Gemini may be crawling your site infrequently or not following your canonicals aggressively. Add schema.org/mainEntity to your current product page, ensure your sitemap is updated weekly, and explicitly mark outdated pages with <meta name="robots" content="noindex"> rather than relying on canonicals alone. If the stale version still dominates, you may need to request re-crawl via Google Search Console or contact Google's AI Overviews team directly—answer engines sometimes lock onto older indexed versions if they perceive them as more 'authoritative' than recent updates.
