Hello, @david,
I have debugged your issue in every possible way and found that if there are multiple columns in a row and only one column have content and the rest of the column are empty then the content not clickable.
I have again checked all the plugins I delete the WP Bakery plugin and install it again but the issue is not resolved. Then I fix your issue using custom CSS code. I set the z-index on the content so that it will appear above and be clickable now.
Your issue is resolved now please check back to your site after clearing the browser cache. Here is the video for a better reference: https://streamable.com/ze4hpl

Here is the custom CSS code that I added to solve your issue: https://postimg.cc/YvgDrZGM
