h3.widget-title not responsive

We are enjoying the Moesia theme as it gives so many options to design a website that looks like 2018. We do have a question as we have been checking it in mobile view. When you have a longer h3 widget title it doesn’t seem to be resizing the title for cell phone view. The title on the above page is Invited Presentations and it resizes fine for tablet but for cell phone is has the “s” come down to a third line. If it did a smaller font it would keep it on two lines and not break up the word. I have tried to add @media but I received a message back stating that I do not have permissions to change the font size. Any suggestions would be greatly appreciated!

Thank you,
