Adobe Portfolio

I will post here since I cannot find a board for the Adobe Portfolio. 

I have a question regarding the use of text boxes in Adobe Portfolio. I cannot find a way to adjust the font size of the page title, previewed in the ´collection´ tab. (see screenshot attached).  I would like to have a smaller font size, because I think it´s ugly like this. 

Hopefully someone can help me,

regards,
