Hey Robert,
Welcome back and thanks for reaching out. I took a look at your site and the lines for the day boxes appear to be there. (see screenshot below)

If you’re ever having styling issues, I recommend watching this YouTube Video on using the ‘Inspect’ tool to identify CSS classes and IDs so you can make changes by adding code to your theme options CSS panel or directly into your theme’s style.css file.
I hope this helps and please let me know if you’re still having troubles. Take care and have a good evening. Cheers 🙂
