Removing blog post titles

Hi

Is there a way I can remove all blog post titles and the ‘admin’ name at the top of each post? They seem to be pushing the page content down and it looks a bit odd having 2 titles there repeating themselves.

Please see https://lovefamilyholidays.co.uk/flight-delay-compensation/ for an example.

The same with posts, please see https://lovefamilyholidays.co.uk/o76-off-suncamp-holidays-accommodation-voucher-codes/

And with wp adverts posts, please see https://lovefamilyholidays.co.uk/advert/blau-punta-reina-child-friendly-resort-spain/

Just wanting to get rid of the clickable titles (second one down with the click and admin word) in all of these if possible.

Thanks

Sally
