Your theme has bundled outdated copies of WooCommerce template files – if you encounter functionality issues on the frontend this could be the reason. Ensure you update or remove them (in general we recommend only bundling the template files you actually need to customize). See the system report for full details.
This is not a major warning. There is nothing to be worried about. The file which called outdated have a comment to mention the compatible version of WooCommerce. The comment is something like @version 2.1.0. You can open the file and write 2.2.10 instead of 2.1.0.
