Upfront Not Scrolling Down The Page In Edit Mode

I have created my own theme using the builder and have it active on this site. Yesterday we could go in to edit mode in Upfront and scroll down the page to edit items further down.

However, today it will not scroll. I have ensured that everything is updated on the site (plugins and themes), as well I have turned off all plugins and tested to see if there is a conflict, but that did not remedy the issue either. I have done a search but could not see this issue posted anywhere.

Is there an update that needs to occur with the theme I built using the builder? Or is there a different issue?

I have granted access.

Thanks for your assistance! I look forward to more information.
