_wpcf7_is_ajax_call – search console

hello, search console has started reporting indexing errors on pages using a CF7 query string.

https://indigocarhire.co.uk/blog/page/106/?_wpcf7_is_ajax_call=1&_wpcf7=5122&_wpcf7_request_ver=1474675200037

The page itself is fine but can you offer any advice as to why this is happening?

Thanks
