Google added the word "First" to my page title

Recently I noticed a few of my page titles were changed in Google search, unlike appending website name to the title, Google added the word "First" at the beginning.

Original title: My page title
In Google serp: First - My page title

Anyone noticed it as well?

I haven't noticed this specific change but Google has been dynamically changing title tags for a long time in many different ways so I am not surprised.

Is it changing your title or is it using some anchor text from elsewhere? I haven't checked titles but descriptive text is often from another source.
