Hi Bradfordlad,
I just seen this post and checked myself. I will raise it with webdev in the morning as they upgraded the calculator today.
I noticed on my phone there was the same problem, clearing my browser history fixed it. Hopefully it will do the same for you!
For future issues please read the original post and create a separate thread, it helps the admins keep track of resolved issues 🙂
Cheers,
Caan
