Title category Yoast doesn′t work

Congratulation for events manager plugin, it′s great to use it. I have a little problem with the title of the category as a page. The tittle seo name of Yoast plugin for the category doesn′t show, however only appears the name of the category. Does anyone know to resolve this problem?

For example in this page https://www.ocioon.com/categoria/conciertos-malaga/ doesn′t show the title of seo like font code show.

Appears Conciertos – I want to show “Agenda de conciertos en Málaga..” as font code show it
