Indexed though blocked by robots.txt

Hello, 

It's been a while since I've been facing this issue and there seems to be no solution. I've submitted a sitemap of my website to Google Search Console which was successful, but every time I request Google to index my website, it always ends up with a warning "Indexed, though blocked by robots.txt" meaning the site isn't indexed by Google. (My site is https://mastercarsreview.com/)

Did anyone face such problem? How did you fix it?

Thank you so much in advance. I really need help in this. (I've sent several emails to both squarespace and google, nothing changed)

Just leave them because that’s not going to hurt your site in any way. In this case, what new GSC is reporting is what’s happening with your site and giving you some information to improve your site. They are blocked by the robots.txt file and the Google bot respects robots.txt and does not crawl those pages but they will be indexed in a scenario when those URLs could be linked to from other pages on your site. In this situation Google will index if they are linked to from external url source as well. Better to click the "Fix Coverage issues".

Why doesn't Squarespace make sure those pages are not indexed? That would remove the error message.
