Product variant id add to my URL when i don't have variants

Hello, I noticed this week that my URLs have changed. They now have a variant id at the end and none of my products are now indexed. I recently changed my theme from Dawn to Horizon. How do i change the URLs back or do i just resubmit my sitemap and wait for them all to be re-indexed?

Could you please share your store URL and password [if applicable] so that I can take a look and provide you with a solution code.

Looking forward to hearing back from you.

Thanks
