Calendly not showing in full

Hi,

I am trying to switch the current scheduling calendar to Calendly. The Calendly is only showing partly on the page. It looks like it has been embedded into a window that is smaller than its size. There is a scroll bar by Calendly.
How can I fix this? I used CSS, but it doesn't work.
I also wanted to know if I can remove the second column on the page and have only one like I have on the home page.

The URL is https://www.connectingfragments.com/

Thank you in advance.
