Why does my dropdown arrow appear as a question mark

I’m using a brix template in webflow and after editing the text of one dropdown, it leaves a question mark instead of the arrow. How do I get it back to the down arrow?

Here is my site Read-Only: LINK

Hi Heather, you didn’t share your published or read-only project links so it’s impossible to see. However if it’s a square box around a question mark, that typically is how fonts represent when the character is unknown.

Chances are you’ve changed the font and that down-arrow character does not exist in the new font.
