Broken site — Google Shopping feed

Hi

I have a rather urgent and unusual issue.

https://www.hatsfromoz.com.au/edgy-silver-fascinator-by-fillies-collection/

Open page source and look for “hreflang”

https://www.hatsfromoz.com/edgy-silver-fascinator-by-fillies-collection/?utm_source=Google%20Shopping&utm_campaign=Googel%20Product%20Feed&utm_medium=cpc&utm_term=159981" hreflang="en-us" />https://www.hatsfromoz.com.au/edgy-silver-fascinator-by-fillies-collection/?utm_source=Google%20Shopping&utm_campaign=Googel%20Product%20Feed&utm_medium=cpc&utm_term=159981" hreflang="en-au" />

As you see, URLs were overwritten with addition of the Google parameters. This completely screwed up my SEO and site ranking.

How do I know it is Feed Pro plugin? utm_campaign is set to “Googel Product Feed”. I accidentally mistyped feed name when creating it. Now, I think problem started about 2 weeks ago. Same feed was working fine for ages.

Any ideas what is happening?

Thanks
