OJS3 Immersion: bold character is not showing


I have noticed that on Immersion the use of bold doesn’t reflect on the website, meaning I cannot add any bold to any text since actually it is not shown on the frontend website (for example, in the footer). On Classic Theme and HealthScience, this actually works. Is there a way to re-establish the possibility to use the bold? With some moderation it can be very useful in some contexts.
Many thanks and best regards,
