Website title including extra information?

When searching for my website on google, you’ll see extra information is added:

https://www.google.com/search?q=mass+mosaic&oq=mass+mosaic&aqs=chrome.0.69i59j69i57j69i60l4.1238j0j4&sourceid=chrome&espv=210&es_sm=91&ie=UTF-8

The page title/description of my homepage has the text “Results 1-78” added before it. I’ve logged into the backend and confirmed that there is nothing inserted that should be causing this. Is this a bug from the plugin?

Any support is very much appreciated
