Customizing headings

Hi, I used a text box to add text to a page. I used the H2 style for the text. However, when I publish the page, the text shows in all caps. So I went to the advanced styling tab and see that I can edit the H2 tag. The dropdown menu for Text Transform allows me to specify Default, uppercase, or lowercase.

I don’t want all uppercase nor all lowercase. But the Default option is selected by default. How do I go about changing this? Thanks
