Cant edit homepage blurb in Google from “Got any good book reccomendations”

Im setting up a wordpress site, and when my site appears in Google search, it says the Website name and tagline, but below it just says “Got any good book recommendations? Get in touch. Proudly powered by WordPress”

Ive been stuck on this issue for hours with no progress. I tried using RankMath to edit the meta description of the Homepage, and this did nothing.

People have said that you need to delete the text somewhere that says “Got any good book recommendations” etcetera, but there is no text I can find anywhere on my site that even says this.

WordPress official help attributes this problem to Google, saying “Search engines like Google choose what information to select for the search results”, which seems kindve like theyre just passing the buck… Seems pretty clearly a WordPress problem not a Google problem, when its text autogenerated by WordPress that doesnt even appear on my site that is the issue.

Any help would be much appreciated, finding it very frustrating as none of the solutions like using RankMathSEO have worked

Cheers
