Links in Calender Excerpt section not working

I'm using the "List" view for my Calendar Events page. I want to enter text in the "excerpt" section of the Options tab, and include a link to an external website (e.g. venue where the event is being held, etc). I enter the link URL via the Text box "add link" icon, but when it displays, there is no hyperlink (only the text associated with the link displays). Interestingly, if I simply delete the "excerpt" text, and include the hyperlink in the full description of the event, it displays the entire description of the event in the List view, including the hyperlink formatted correctly. However, I don't want all the details about the event displaying in the "List" view - just the hyperlink. Has anyone else encountered and solved this problem, or found a work-around? I'm using the Heights template (Brine family). Thanks!
