Title in the search results

I have a little issue with the title of some articles in the search results on google.
Correct title should be “%title% %sep% | name of the website”

for example: “Il Riccio (2009): un film d’altri tempi! | Gli acchiappafilm.it”
where “Il Riccio (2009): un film d’altri tempi!” is the title
“|” is the separator
“Gli acchiappafilm.it” is the name of the website

for some articles it work right, but for others no. Tt seems that the title is cut after the colon or after the bracket

for example for the title “Richard Jewell (2019): l’eroe semplice di Eastwood | Gli acchiappafilm.it”
on google i see “Richard Jewell – Gli acchiappafilm”.

So i don’t understand which is the problem
