When using the Sitemap.xml file functionality in the SXA module for multi-language sites, enabling the language embedding might result in duplicates in the SXA sitemap.
To mitigate the issue, consider the following options:
- Upgrade your instance to SXA 10.3 or later
- For SXA 10.2, download and install the corresponding cumulative hotfix available in KB1001757
- For SXA 10.1, download and install the corresponding cumulative hotfix available in KB1001756
