Post Title Missalignment since last WP update

Since the last update, I notice that some of my post titles are out of alignment.

Please see this page for an example

https://cthreeeurope.com/2015/08/28/incorporating-the-sinclair-method-into-alcohol-treatment-a-practical-experience-from-a-uk-alcohol-treatment-practitioner/

I am not technically minded so I don’t mess with any setting so I know that this isn’t something I have done.

Can anyone please tell me how to correct it?
